Police are searching for a suspect wanted in connection with several violent subway robberies over the last two weeks on A and C trains in Harlem.
According to police, the suspect asks his victims for the time and then proceeds to assault them. The suspect has struck four times since July 23, including one attempted robbery.
The victims have all been attacked between 110 and 125th streets. One victim suffered a broken jaw and eye socket before the suspect fled with his property.
That victim, who asked not to be identified, told NBC 4 New York he was in shock after the assault.
"I don't know why he attacked," he said. "He didn't talk to me before... he just point and then took my phone."
The man's recovery is expected to take at least several weeks.
In another one of the robberies, the victim suffered a punctured lung and broken ribs.
Police have released surveillance video they say captured the suspect's image (see above).
Anyone with information on the suspect is asked to call Crime Stoppers at 1-800-577-TIPS (8477).
