Police need the public’s help to track down a group they say attacked and robbed a man during a drug deal in Gravesend.

It happened on March 3 just after 6 p.m.

According to police, the 29-year-old victim met a male and a female to purchase marijuana along West 12th Street.

Police say the three of them started walking when two men ran behind them and knocked the victim to the ground.

That’s when police say all four suspects started to beat the victim, and ran off with his cellphone, wallet and $300.

The victim suffered a broken arm and nose, and was taken to Coney Island Hospital.

Police say the three male suspects were wearing all black that night, and the female suspect had a light-colored jacket and a hair wrap.
