Two teenagers were arrested in relation to a suspected motorcycle theft after one of them was apprehended by actor Tom Hardy.
A witness said the Hollywood star caught one suspect in a dramatic chase through gardens and a building site during the incident on Sunday.
The Metropolitan Police said it arrested the 16-year-old males near the actor’s home in Richmond, southwest London.
It said the two have since been released.
Onlooker Arun Pullen (22) told The Sun newspaper how two youths on a motorbike jumped a red light at a busy junction before crashing into a Mercedes.
He said the 39-year-old Batman star, who was in the area at the time, then “switched into superhero mode”, chasing down one of them before checking him for weapons.
“Tom must have been walking down the road. He went off like a shot in pursuit and looked furious,” he said.
“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.”
Mr Pullen’s girlfriend Kalisha, a fan of the actor, added: “There was no mistaking him.”
