In November 1986, aged just 20, Mike Tyson became the youngest heavyweight boxing champion of all time. Tyson came from a troubled upbringing in New York and only found a direction in life when he met the legendary trainer, Cus D'Amato. But, after D'Amato's death, Tyson's career was marred by a rape conviction and an ongoing battle with drink and drugs. He talks to the BBC Boxing Correspondent, Mike Costello.
