Bret Hart’s attacker at last night’s WWE Hall of Fame induction has been identified as Zachary Madsen and is currently being held at the 78th Precinct in Brookyln, New York, according to a report from CBS New York.

The report notes that a security guard received minor injuries in the melee that was sparked when Madsen, an amateur MMA fighter, charged into the ring and attacked Hart.

Madsen has been charged with two counts of assault, as well as trespassing.
