Shamed boxer Mike Tyson has been sentenced to 24 hours in jail and three years' probation after pleading guilty to drug possession and driving under the influence (DUI) in relation to a 2006 arrest. The 41-year-old former heavyweight champion was arrested last year (06) following a traffic stop outside a Scottsdale, Arizona club. He entered his plea at a hearing in September (07) after being charged with one felony count of cocaine possession and one misdemeanour count of DUI. Tyson has since been seeking treatment at an inpatient facility program for "various addictions", as well as attending Alcoholics Anonymous and Narcotics Anonymous meetings, according to his lawyer David Chesnoff. Chesnoff also claimed Tyson had taken 29 drug tests since the 2006 incident, with all results coming back negative. Prosecutor Shane Krausner appealed to Arizona's Superior Court Judge Helene Abrams on Monday (19Nov07) to sentence Tyson to one year in jail, stating that the former boxer was a multiple offender who had previously been convicted of a violent crime. But Tyson escaped the maximum sentence of four years and three months behind bars, after Abrams praised the disgraced star for taking action against his drug problems and ruled he must spend just one day in jail. Prior to delivering the sentence, Abrams told Tyson: "You worked to address your addiction and self-destructive behaviour." Tyson has a previous conviction for rape in Indiana in 1992 and in 1999, he pleaded no contest to misdemeanour assault charges in Maryland. He is also infamous for biting off a chunk of fellow boxer Evander Holyfield's ear during a fight in 1997.
