19-year-old Max Edward Hartley is under arrest for allegedly assaulting the famous one-armed drummer of the legendary British rock group Def Leppard.

The assault occurred when 59-year-old drummer Rick Allen was staying at the Four Seasons hotel in Fort Lauderdale Beach.

He went outside for a cigarette when Hartley attacked him. Hartley allegedly ran at Allen at full speed, striking him and knocking him backward, causing him to hit his head on the ground.

Police say a woman tried to come out of the hotel and aid Allen, but Hartley knocked her down as well.

Hartley was arrested and taken to Broward County Jail, and he’s being charged with two counts of battery, four counts of criminal mischief, and abusing an elderly or disabled adult.
