'Prince' Naseem Hamed was a boxing phenomenon, his speed and power carrying him to the world title. It also backed up his legendary big mouth. However in 2006 he was rather more contrite when sentenced to 15 months for dangerous driving. He smashed head first into another car while trying to overtake at 90mph injuring every major bone in the other driver's body. He was released after serving 16 weeks and was tagged for the remainder of his sentence.
