The charges and a lawsuit stem from an alleged Jan. 21 gambling dispute.
The lawsuit, filed by the victim, claims Broner lost thousands of dollars in bowling bets to the victim. Broner suggested they play one last game for a $6,000 wager, but the victim refused.
“At that time, Broner became upset and left the bowling alley,” the lawsuit states. “When [victim] left the building around 3:00 a.m., Broner was waiting for Carson in the parking lot with approximately eight other individuals.”
After demanding money, Broner allegedly punched the man in the face and neck, brandished a handgun then fled the scene.
The man claims his $10,000 in cash was missing when he regained consciousness. He did not call police, but received stitches at the emergency room, TMZ reports.
Broner and the victim had been friends for two years.
