A terrified rider captured the aftermath of the weekend shooting on his cellphone as police officers tended to the two men lying on the ground at the 182nd-183rd Street subway station by the B and D lines. Above ground, a nearby business caught the moment emergency crews converged on the station entrance and brought the two men out on stretchers. Police say the victim is expected to survive but the alleged armed robber was last listed in critical condition. A law enforcement source identified the gunman as a gang member with a lengthy criminal history. They add he's been arrested three times since 2018 for armed robbery and attempted murder in one of those cases.
