He beat up seven prostitutes once when he was high.
The assault, which took place in a hotel room in 2009, occurred after Tyson used morphine, cocaine, and alcohol. He credits the incident with helping him get sober. "It was the lowest point of a very low life," he told Robin Leach in an interview in April 2012, "but it was my own knockout punch to clean up life, get whole, get well-and I haven't done anything in three years now. I'm clean. I'm sober."
