British actor Danny John-Jules is in police custody after allegedly attacking a refuse collector with a knife. Neighbours in London's Kensal Rise claim John-Jules, the star of British cult sci-fi series Red Dwarf, rushed out of his home wearing only a bathrobe and threatened garbage men with a knife. A witness tells British newspaper The Sun, "At first it sounded like a petty argument. I saw it was Danny and he was wearing his dressing gown but it was early and I didn't think much about it. "I looked out of the window and it was terrifying to watch. I've seen Danny in the street a few times and he's always been very friendly and normal. It was shocking to see him behave that way - he must have flipped." Authorities have confirmed they arrested the 47-year-old on suspicion of causing actual bodily harm. His victim was taken to the hospital with minor injuries.
