PARK SLOPE, BROOKLYN — They stole headphones off a woman walking down the street, they reached into a man's car and tried to grab his phone and they pushed a deliveryman off his bicycle.

A group of troublemakers went wild for 10 minutes near the Barclays Center on Feb. 5, and now police want help tracking them down. NYPD on Monday released a photo of one youthful suspect, who appears to be between 14 and 16. They believe he was part of a group that approached a woman, 36, walking near Fourth Avenue and Atlantic Avenue.

One member of the group grabbed headphones off the woman's head and ran off with his companions toward The Atlantic Mall, police said. That was at about 7:50 p.m. — five minutes later a man sitting in his car at P.C. Richard & Son saw his driver's door open, police said. The group had opened his door and they tried to grab his phone from his hand, authorities said.

The miscreants ran off toward Pacific Street, according to police. Within five minutes, they pushed a bicycle deliveryman, 20, off his bike near Modell's Sporting Goods, police said. They assaulted the man and took money and food from him, according to police. Medics treated the man at the scene, police said.
