Police on the Upper East Side are looking for a man who's been stealing people's iPhones - from his bicycle.
Authorities say the suspect rides his bicycle up to people on the street and snatches away their Apple phone.
Police have released surveillance video of the suspect taken just before the most recent incident on Tuesday afternoon. The theft took place at the East River and East 94th Street.
Police say the man has been involved in 18 robberies since January.
All of them have taken place on the Upper East Side, and all but one of the victims have been women.
Police are asking anyone with information to call the Crime Stoppers hotline at 1-800-577-TIPS.
