and that is why, carol, it stuck into the motorbike taxi driver's head so much. and when he saw the footage all over the television screen, he recognized this man. now i live here. normally what you do is you hand over an address in thai. i've often had to go places and i've looked up the address in thai or asked people that speak thai. it does seem strange that this was written, lumpini park, just those two words written on paper. was that because the man wanted to conceal his voice? strangely enough, he did then speak on his cell phone in a language the taxi driver said was not thai or english. police want tourists and local people to come together as well to help them track these men down. they're using the model of the boston bombing.
in the last few minutes that perhaps they are doing that to block the view, to protect him while he plants the bomb. then they all seem to leave within minutes of one another. and then shortly after that the bomb goes off. we've also spoken to that motorbike taxi driver who believed he took the main suspect in the yellow t-shirt away from the scene. he handed him the note written in english. it said on it lumpini park in english. that is a main park in bangkok, much like central park in new york or hyde park in london. and that is where the man got off. in that journey he was speaking on his mobile phone in a language the motorbike taxi driver has told cnn he could not identify as thai or english. >> i'm curious, is it strange that this man handed the taxi driver a note written in english? >> absolutely.
