Suffolk County police say two people in gorilla costumes and a third in a chicken suit took the boy's bike Monday in Rocky Point, on the north shore of Long Island.
Police say the three confronted him while he was riding along Route 25A around 1:15 p.m. Police say one of the gorilla-suit suspects punched the teen in the head and knocked him off his bike, and the person in a chicken costume rode off on it. The ape-suit duo ran away.
The teen was treated at a hospital for minor injuries. He's been released.
Detectives are searching for the suspects.
