A concert featuring former Dipset member Max B. was halted when gunshots rang out at S.O.B's in New York tonight (July 22).

Witnesses told AllHipHop.com that an entourage of men entered the club just a few hours ago, during Max B.'s performance then shots were fired inside the club.

“They came in 25 deep, a couple of songs were playing and a guy was in Max's face in VIP making gestures,” one witness told AllHipHop.com. “One thing led to another and the whole crew bumrushed (ran up to) the security and VIP and everyone started fighting. That's when a single shot was let off.”

Patrons exited the club frantically and at press time, it was not clear if there were any injuries or fatalities.

Approximately 30 police cars presently cover SOB’s with other officers on horseback. The Varick Street block in New York, where the popular club resides, has been blocked off. No suspects have been named in the incident.

SOB’s has been a staple in Hip-Hop and currently celebrates its 25th anniversary.
