Cops are hunting for a creep who exposed himself and groped a 13-year-old girl in The Bronx, police said Thursday.

The perv approached the teenager near Crotona Avenue and asked for directions to Crotona Park — a block away — at around 4:45 p.m. on Jan. 6, cops said.

The girl escorted him to the park, where he then groped her private area and exposed his penis before fleeing, authorities said. The victim sought help from someone at a nearby school. She was uninjured.

The attacker was last seen wearing a black hooded jacket, blue jeans, a black backpack and black sneakers.

Anyone with information is asked to call the NYPD’s Crime Stoppers Hotline at 1-800-577-TIPS (8477).
