According to the publication, Hardy grabbed one of two teenagers who fled after the stolen bike ran into a vehicle, while the other was apprehended by police.
"He went off like a shot in pursuit and looked furious," a witness told U.K.'s The Sun. "I asked Tom what happened and he told me he chased him through my back garden and caught him around the block -- but the route was like an assault course."
"We can confirm that there were two people on a stolen moped that went through a red light and crashed into another vehicle," a spokesman for Richmond police noted. "The males ran off and one was detained by Tom Hardy."
Way to go, Tom!
