Videos catch Katt Williams in onstage tackle at Philly concert

Comedian Katt Williams has had a rough month - and it got rougher Sunday night in Philadelphia, after he jumped a man onstage at rapper Beanie Sigel's show at the Trocadero.

The incident, caught on several smartphones, showed Williams, 44, flying at a member of Sigel's entourage and tackling him to the ground, as surprised bystanders circled around and bodyguards rushed to intervene. The ambush happened toward the end of Sigel's show, a celebration of Sigel's 42nd birthday, which drew performers including Jadakiss and Lil Mo.

A police spokeswoman said she did not immediately have details on the incident.

Concertgoers posted other video online of Williams, before the melee, dancing wildly and dropping to do push-ups on the stage.

The incident comes a week after he was arrested in Georgia for allegedly punching a pool-supply employee in Gainesville during an argument. Also last week, five women accused him of holding them up at gunpoint and stealing their cellphones in Atlanta. They told police they asked Williams to pose for photos with them - but that he grew angry when one began filming the encounter and started fighting the women. But Williams told police that the women harassed and filmed him without his consent and threatened him.

Williams, an Ohio native whose real name is Micah Williams, was in Atlanta as part of his ongoing Conspiracy Theory tour.

Williams also has feuded with comedian Kevin Hart, after he called him a "puppet" and issued a $5 million comedy challenge to Hart via social media. Williams later apologized to Hart.
