UPPER ARLINGTON, (AP) — Olympic gymnastics champion Paul Hamm has been accused of hitting and kicking a taxi driver in suburban Columbus, damaging a cab window and refusing to pay a $23 fare.

The 28-year-old Hamm can be heard on an Upper Arlington police video telling an officer he’d had about eight drinks, WBNS-TV in Columbus reported. As Hamm sits handcuffed in the back of a cruiser, he asks officers to let him go and says, “I don’t understand. I’m gonna kill you guys.”

Hamm, who is working as an assistant coach at Ohio State while he trains for the London Olympics, is charged with assault and two other misdemeanors. He was charged Saturday and is free on bond awaiting a Sept. 15 arraignment, according to online court records.

His agent, Sheryl Shade, declined to comment Wednesday.
