After the fbi launched the manhunt to find him and issued a cell phone alert to millions of people across the state. You also have this surveillance picture believed to be rahami in new york moments before an explosion detonated. This is the one saturday night, chelsea neighborhood, Downtown Manhattan, 29 people were hurt in the blast. You see just glass, you know, windows, cars, businesses, shattered. Just a couple blocks away there was another Pressure Cooker sort of device that was found. That never went off. Rahami is also being questioned to possible ties to other improvised bombs. A blast that happened at the start of a charity race in seaside park, new jersey, on saturday, which didnt begin on time, thank goodness, because of issues with registration. Then you have these five pipe boms that were found in a train station overnight. One of those devices inadvertently detonated by a bomb squad robot. Now police want to know if rahami built these bombs himself, and perhaps most urgently if, in fact, he acted alone or if he had help. Lets begin our coverage with jean casarez at the scene of the capture in linden. Jean, i know there was a fingerprint that led to the i. D. Of this man and then the be on the lookout. Tell me about the man who saw this guy at asleep at a bar because he had been watching cnn. Reporter what were finding is its a tip. Its a tip that actually led them to this area. Its a very residential area here in linden, new jersey. I spoke with some neighbors just a minute ago and they said this morning there were shots, so many shots. As we heard new york Law Enforcement officials just said its very excellent that he was taken alive and he was taken down right here in this sleepy little neighborhood thats filled with families, with children. Very close while this was happening this morning, and we will tell you that four officers were injured along with rahami, and theyve been transported to two different hospitals, but about three miles away is where rahami and his family lived, at the First American chicken restaurant. They own it. The mayor of elizabeth, new jersey, told me that the family lived on the upper floor. This morning while this was happening here, the fbi was executing a search warrant at their home. At least one box of evidence, two cars were towed away. They stayed there for hours executing that search warrant. Very important to them. And then i will tell you that one mile away from the chicken restaurant is where the bombs were discovered this morning a backpack. It was actually 9 30 last night that two homeless men, i am told bit mayor of elizabeth, new jersey, were walking. They found the backpack in the trash can. They took it out. They took it under the railroad tracks. They opened it up and there they saw a pipe and wires. These two men, i was told, literally ran to the Police Department and told them, this is something serious. And that is what got the bomb squad out. That is how they detonated at least one, secured the five bombs that were in there, so no one was injured in all of that. They are now packaged securely and will be on their way as possibly evidence in a criminal trial against this man that they just captured this morning. No charges yet, however. But Law Enforcement just said federal charges may be coming. Brooke . All right, jean casarez in linden, thank you, jean. Now, this bombing suspect was injured in that shootout with police. Four other officers were also hurt. All were rushed to hospitals for treatment. Lets go to cnns brendan joining us from new jersey hospital where the suspect was taken. What do you know . Reporter what were seeing just outside the hospital is a heavy police presence, which weve seen all over the place. Officers standing here, making sure every car that goes inside the car at the hospital is checked and made sure theyre allowed to be in there. Thats likely because rahami is here being treated for those injuries. You showed that video to your viewers. We know he sustained some sort of injury to his shoulder. He was alert and somewhat talking when he was loaded into that ambulance. And then brought here to the hospital. So, we dont know exactly his condition at this point. We dont know if hes even talking to authorities at this point, but undoubtedly, fbi officials are here as part of the investigation. Now leads them to the hospital where hes being treated. We also know at this point that one of the officers that was injured in that takedown, as jean just talked about in nearby linden, one of those officers is also being treated here at the hospital, nonlifethreatening injuries. Thats good. We know the injuries sustained, one officer hit in a bulletproof vest. Another officer shot in the hand. We dont know which officer is here, but we know this is one of the hospitals hes at as well as another hospital in this area, brooke. Brynn, thank you so much in newark. Now were learning a little more about this suspect, about his family, about potential lawsuit. Ive got evan perez here with me here in new york. Our justice correspondent can we first pause for a moment just to reflect on everything thats happened over the past 24 to 48 hours. This race that, thank goodness, didnt go off, the marine corps race raising money saturday morning. The fact that this one bomb that did go off in chelsea in Downtown Manhattan ended up in a dumpster, or else this would have been so much worse. A lot worse. Incredible series of lucky breaks, frankly. The fact that that race started late meant people werent standing near that garbage can, witnessing, waiting for runners to go by, and nobody got hurt when that blast went off. There were three bombs in that garbage can. Only one of them detonated. That was another stroke of luck. Then you have saturday night in chelsea, the bomb that did explode on 23rd street, it happened to be underneath pardon partially underneath a metal dumpster so the dumpster took a lot of the hit. 29 people were injured, but luckily not any serious injuries simply because the force of the blast, even though it shattered windows, damaged cars, there was a lot of damage done there, nobody died. And then, of course, the one on 27th street, according to the press conference there, the information that was given by the fbi and the nypd at that press conference at the top of the hour, they said that someone apparently disturbed the device. It was inside a duffel bag. Thats a duffel bag that rahami was seen pulling on 23rd street as well as 27th street in Surveillance Video. They appear to have taken the device out of the bag, and that might have disturbed it and caused it to not go off s, broo. Someone who owned a bar in linden, new jersey, who found this guy asleep into the entryway of this bar, because he had been watching cnn on his laptop, calls police, dot, dot, dot, the guy gets caught in the shootout. As far as his background, record, family, what do we know . Well, hes afghan background emigrant family as jean casarez was talking about, they lived above this chicken restaurant in elizabeth, nj nlg. In 2011 they filed a lawsuit because they said the town and the Police Officers were harassing them with code violations. It appears the lawsuit went nowhere, but thats really about the extent of the kind of trouble that weve seen with this family or with this suspect. We do know there were a couple minor background minor criminal issues in his background. The police talked about that at the press conference at the top of the hour, but nothing major. No sign of him at all on the fbi radar for radicalization. We do know hes traveled back to afghanistan. Whenever he came back into the country, he would be interviewed. Again, nothing at all that came up. The question, one of the primary questions, did he act alone . Well, at this point they do believe he acted alone. There was some question, we reported earlier certainly from talking to officials, because of those people who were seen on that video handling the device that didnt go off, there was some fear that maybe others were involved. They now believe that those people had nothing to do with it. They still havent found them. They havent talked to them. They want to talk to those people. They right now believe this man acted alone. Evan perez, thank you so much. Well talk again. A witness to the shootout this morning is putting on a microphone right now. He will join me live to tell me what he saw there in linden today. Also ahead, new york on high alert as world leaders, including the president of the United States, are in new york at the u. N. General assembly. Well take you there and talk security.

The arrest of a suspect in bombings in new york and new jersey that left 29 people wounded has been captured alive as investigators are trying to determine if he acted alone. Joining me now, cnn terrorism, paul, pamela wood, certainly ceo of Guidepost Solutions and anthony may with us, retired explosives investigator with the atf. Paul, the last time i laid eyes on you was in nice, france, when horrendous, horrendous attack. I dont know if motivation was similar in terms of maximizing casualties. We made the point this could be a lot worse. Youre most curious about this mans multiple trips back home to afghanistan. Were hearing about multiple trips. We dont quite know what years he was going back, but that will be interesting to investigate as they look to see if he was connected to any overseas terror groups. In the United States he might have been acting alone but that leads to the possibility that he might have had connections overseas, might have met people while in afghanistan. Obviously, afghanistan is a place where a number of terrorist groups have been operating in recent years, notably al qaeda, the Pakistani Taliban were the group that directed the times square attacker in 2010. That car bomb didnt go off. Theyll look at that pattern, see if when he came back, he was, perhaps, showing signs of radicalization. Did that afghanistan travel have an impact . Where did he learn how to make these devices as well . So far, they appear to be quite rudimentary. We dont have full clarity about the chemicals inside the Pressure Cookers yet, though. I think we need more information on that to fully decide how simplistic these bombs were. But could he have got some training overseas or did he just learn to make it all off the internet . As we find out more about the devices, i think well be able to come to that determination. Anthony, as were talking devices, let me pivot to you. Everything youve heard about them, filled with ball bearings, the bb, which was one tie among some of these devices. How would you rate the sophistication level . Well, the sophistication level of the Pressure Cooker device is somewhat higher than what we saw in the seaside pipe bombs. The now, there is some reports coming out that wrappers of taneraite, a product name for an exploding manufactured product, a target product, which would explain some of the issues going on here with the damage were seeing. But as far as sophistication, you know, these arent your highly sophisticated devices. Theyre very they level. They go on a degree of level from crude to somewhat sophisticated. Okay. On the tanerite note, we at cnn do not have that confirmed. Julie, to you, the fact this man is alive, they caught him alive, how do investigators get him to talk . Well, investigators are going to use all their tricks to get him to talk, to try to induce him to cooperate by, you know, offering him a cup of coffee, you know, trying to discuss things with him. It could take a lot of time. They obviously also could use higher pressure tactics. But i also want to get back to the recent travel that he took. I think its very important to look at his travel patterns and compare it to the time of his naturalization. I think a big question to ask the Immigration Service is did they know of his travel, was it to afghanistan, was it to other places, and did they take that into account when he became naturalized . Are there things they could have focused on similar to social media and San Bernardino that they didnt do here. Okay. As far as whether or not he acted alone, paul, or, you know, with a group or was inspired online or, perhaps, there were connections back in afghanistan from his trips, how do they determine all of that and how quickly can we know . Well, theyll be interviewing him, first of all, trying to get information from him as quickly as possible. Theyll be interviewing many associates, everybody they can find, theyll be looking at his computers, his cell phones, his social media history, theyll be involving foreign and Intelligent Services in afghanistan, he probably traveled through pakistan hes on no list for anything of that nature. Not at all. He was not on the radar screen. They were very firm on that, that he was not known for either radicalization or someone that was under investigation in any way, shape or form. And thats a nightmare scenario for Intelligence Services here in the United States, socalled clean skins. Very difficult to sort of see this kind of attack coming if they are not on the radar screen. You really sort of have to depend on either somebody close to someone tipping off police or to see something worrying on their social media. Otherwise if hes just acting alone, pretty much impossible to intercept a plot like this. Julie, whats your take, at this stage how do investigators determine if theres an actual cell as opposed to someone who is just communicating with accomplices . Well, theyre going to use all their resources. Theyre going to look at foreign intelligence. Theyre going to look at individuals arrested in the car and theyre going to try to get information from him. You know, my understanding is he was identified in part based on a fingerprint left on one of these bombs, so he wasnt very careful. So, perhaps there are other things above the american chicken shack that would lead us to his accomplices to folks he worked with. It was a fingerprint. We dont know if it was on the device or the cell phones, but thats what ultimately led them to i. D. ing and the botlo. Were starting to see that more frequently than we used to. We saw that a lot in afghanistan and iraq theater of operation. Cell phones were used to initiate and detonate devices. A cell phone has a variety of capabilities. You can use it use the internal clock or timing mechanism alarm on a cell phone to initiate a device or you can use the cell phone itself, the receiver as a remote command detonating type system. A cell phone is very versatile. Provides the bomber a lot of opportunities there. What about, julie, just the timing of these bombs or wouldbe bombs and the locations. Ive been in contact with someone within nypd and thats sort of the Million Dollar question as far as the significance. What do you make of it . Its really hard to tell at this point. Certainly this ans an important time, given the u. N. General assembly, the president coming to town. You know, i think the locations do show one thing, though, that soft targets are the new norm. Theres been so much security around critical infrastructure, so this individual was able to focus on areas that were softer targets. I think that has to be a warning to those that operate businesses or malls. What sort of things do you have in place . And i think the technology that abled us to identify him, the cameras, the fingerprints, all of those pieces have become more and more important. As to why he did this on a saturday night and then bombs later o i think that is the Million Dollar question. You would think that he might want to do it at a time when there was more activity unless he was trying to do a dry run, but as you can see, dry run doesnt work very well when you have the fbi and nypd on it. I mean, can we just pause for a moment. It is extraordinary how quickly nypd, fbi, joint Terrorism Task force, jumped on this and found him. I mean, i absolutely. It was like that. Its amazing. Its amazing. Technology played a big part. The cameras, the fingerprints. But also individuals in that elizabeth, new jersey, train station. They saw a backpack that looked interesting, what was in there and they knew they have to say something, to call police. So, i think all of thos
