The video shows the suspect wanted in at least four robberies around Chelsea.
The man is in his mid 30s, between 5-foot-5 and 6-feet tall, weighing 220 pounds. He is bald and has a stocky build.
Detectives say he attacks from behind, clubbing and choking his victims.
Three of the victims have been elderly men, one of whom suffered a stroke.
The first incident happened on August 13 around 7:30 a.m. at Broadway and West 28th Street. The suspect approached an elderly male from behind as he entered the N train subway entrance and choked him from behind, removing the victim's wallet. The suspect fled on foot in unknown direction. That victim sustained a stroke as a result of this incident.
Then, on August 16 at approximately 3:45 p.m. at 1178 Broadway (Urban Living), the suspect followed an elderly male into an elevator in a commercial establishment and choked him from behind, removing currency and a cell phone. The suspect fled on foot in unknown direction. There were no injuries as a result of this incident.
The suspect also struck on August 18 at Broadway and West 28th Street and August 21 at 8th Avenue and West 23rd Street. Both of those crimes fit the same M.O. as the others.
