Rapper Rich Homie Quan has been caught on camera appearing to slap a fan during a concert in Wisconsin last week (ends04Jul14).

The hip-hop star celebrated America's Independence Day holiday by performing at the 3 Monkeys venue in Racine on Friday (04Jul14), but he halted the show after one overzealous man attempted to grab his arm.

Quan was filmed allegedly lashing out at the male, before stopping the music and addressing the incident, telling the crowd, "I thought he was trying to shake my hand. N**ga trying to get onstage (sic)."

It's not the first time a violent incident has taken place at Quan's concerts - two males were shot dead during a March (14) show in New Orleans, Louisiana, while a pair of fans were injured at a gig in Missouri in January (14), just weeks after another devotee was killed in Ohio in December (13).
