Slim 400 Shooting Captured on Video, Suspect Fired Several Rounds

Slim 400 was the victim of what appears to be an ambush attack as he sat in a driveway ... only to be surprised and shot at multiple times.

Law enforcement sources confirm a video floating around online is the Slim 400 attack. You see the suspect walk up the driveway, gun in hand, and approach the driver's side of the vehicle, where Slim was seated.

It's unclear exactly what happens next, but you see a flash and hear a gun go off and Slim lunge at the suspect. Gunshots continue to go off as the rapper continues to move toward the street with the gunman.

As we reported, Inglewood PD responded to a call of shots fired Wednesday night, and discovered Slim in bad shape in a driveway. We're told he was transported to a local hospital where he was pronounced dead.
