Chris Brown Sued: I Got Shot Because You're a Gang Member

Chris Brown's known gang ties set off the shooting spree inside 1 OAK, and the club should have done a better job screening for weapons ... according to one of the shooting victims.

Ginja Elms says he was among those shot in 2014 at 1 OAK on Sunset -- the same night Suge Knight got popped 7 times. In a lawsuit he's filed against Brown, Elms says the nightclub was well aware of the singer's gang affiliation, and as a result it should have patted down every single person entering that night ... including celebs and their crews.

He's also suing singer Pia Mia, who co-hosted the event with Brown. You'll recall Suge already filed a very similar suit against Brown, Mia and 1 OAK.

Aside from the obvious gunshot wound, Elms says he's suffered "disruption in his relationship with his wife."

He's suing for damages in excess of $750k.
