Bobby Shmurda was just busted again … this time for marijuana — but the “Shmoney Dance” rapper believes NYC cops have a vendetta.

The 20-year-old was busted for smoking a joint with two friends while double parked on a Brooklyn street … and Shmurda was hauled off to jail for the night.

Sources close to the rapper say that Bobby believes neighborhood cops are out to get him — not because he’s black — because he’s a big music star and they want to see him fail.

As we previously reported Shmurda was busted in June on a felony gun charge … after he was caught brandishing a 9mm Glock.

After he was released from jail, Bobby posted a video saying it’s gonna take more than a few “bum ass” cops to slow his roll.

That will clearly help his case.
