Daniel Radcliffe came to the aid of a tourist who was targeted by thieves in London, according to an eyewitness.
The Harry Potter star was one of a number of people who went to assist the man who, according to police, suffered a cut to the face during the incident.
The man, aged in his 50s, was attacked by two people on a moped who snatched his bag before riding off.
Witness David Videcette said Radcliffe had consoled the victim and identified himself upon request.
“It was a bit of a surreal moment,” Mr Videcette told the Evening Standard.
“I said ‘you’re Daniel Radcliffe’ and he replied ‘I am’.”
Mr Videcette, a former Metropolitan Police detective who now writes crime novels, said he had seen the moped riders acting suspiciously before they struck.
“I realised they were getting ready to do something” he told the London newspaper.
“Then one of them gets off and attacks a man with an expensive-looking Louis Vuitton bag on the pavement.
“They slashed him in the face with the knife and made off down the King’s Road [in Chelsea].”
Mr Videcette, who was in a car at the time, said he had unsuccessfully attempted to ram and follow the moped before returning to the scene and encountering Radcliffe.
The incident, which took place on Friday evening, follows a spate of muggings and acid attacks in London involving suspects riding mopeds.
Radcliffe’s spokeswoman confirmed the 27-year-old was present but made no further comment.
Earlier this year it was reported that actor Tom Hardy helped to apprehend a man who had allegedly stolen a motorbike in Richmond in south-west London.
