Former police officer David Videcette was also on the scene and reportedly tried to apprehend the attackers before the two made an escape through multiple red lights. That’s when he recognized the British actor, who was consoling the victim. 
“It was a bit of the surreal moment, I said, ‘You’re Daniel Radcliffe’ and he replied, ‘I am,’” Videcette recalled to the Evening Standard. “He was a really nice bloke, a lot of stars wouldn’t have stopped to help.”
