Mike Tyson was found guilty Friday of threatening a guard and disorderly conduct after a hearing in the Indiana Youth Center at Plainfield, Ind.
As a result, the former heavyweight boxing champion will lose good-credit time, delaying his earliest release date 15 days, to April 9, 1995.
Tyson, serving a six-year sentence for rape, pleaded not guilty to one count accusing him of threatening a prison guard and guilty to a second charge that he threatened staff members when he was taken to the supervisor's office to discuss the first incident.
The hearing officer found Tyson guilty of the second charge, a Class B offense, and reduced the first charge to disorderly conduct, a Class C violation. He was ordered to spend 10 days in the prison's segregation unit, but that sentence was reduced to the five days already served.
Also, a federal judge in New York said Tyson's mounting legal bills might force him to freeze the remaining $1.8 million in Tyson's annuity. Tyson's former manager, Bill Cayton, asked U.S. District Judge John Keenan to attach the policy in the event Cayton wins a judgment against Tyson in court. Tyson and Cayton, whose contract expired in February, are suing one another.
