He will be on parole until September, followed by two years' probation that includes 200 hours of community service.

Tyson [left] leaves jail with a friend

The Maryland Parole Commission voted 5-1 to grant Tyson's release.

The boxer was jailed in February after pleading no contest to assault charges following a traffic accident in the Washington suburb of Gaithersburg.

Tyson punched a 62-year-old driver in the jaw and kicked a 50-year-old man in the groin after his wife's Mercedes was involved in a three-vehicle crash last August.

Judge Stephen Johnson said the boxer had demonstrated ''potentially lethal road rage".

Rape conviction

Tyson was sentenced to one year in the Montgomery County jail. But another 60 days were later added on as punishment for violating probation for his 1992 rape conviction.

The boxer was released on condition he undergo a psychiatric evaluation and treatment to learn to control his anger, an official said.

He will also be subject to urine testing at least twice a week and unannounced home visits by state authorities.

Plans are afoot for Tyson to return to the ring. His last fight, a fifth round knockout of South African Francois Botha, took place shortly before his return to jail.
