Manhattan detectives are on the hunt for the violent robber who choked out his victims and stole their luxury watches in three separate robberies this summer. The NYPD released images Tuesday night of the suspect behind the pattern of robberies, the most recent of which occurred at the 14th Street station on the 1 line in Greenwich Village at about 1:05 a.m.

on Aug. 9. In that incident, police reported, the suspect approached a 26-year-old man from behind and wrapped him in a chokehold, eventually knocking the man out cold.

The incident was reported to NYPD Transit District 2 and the 13th Precinct . The victim, who regained consciousness, was brought to NewYork-Presbyterian Lower Manhattan Hospital for treatment of pain; he was listed in stable condition.

on June 15, police reported, a thief choked a 29-year-old man unconscious at 147 Christopher St., then stole the man’s watch and fled the scene. The victim was revived but did not suffer serious injury.

Nearly a month later, at about 2:40 a.m. on July 14, cops said that the choke artist struck again — strangling a 27-year-old man from beh.
