WWE UK Champion Pete Dunne is something of a fighting champ … which he put on full display Saturday at Download Festival by fighting Mark Andrews during his band’s set.

Andrews was performing with Junior at the British music festival before their championship match tonight, when Dunne hit the stage and attacked him — evoking boos from the crowd.

Pete tried to make his escape afterward, but Andrews was quick to retaliate by flipping off the stage and onto his attacker. Mark then got on the mic and promised to win their match tonight.

Check out footage of the incident — including that awesome stage flip — below.
