Mike Tyson

FORMER World heavyweight boxing champion Mike Tyson's psychiatrist has sued him for allegedly failing to pay 29,000 dollars in therapy bills, court documents showed.

Analyst Mitchell Gibson alleges that Tyson failed to stump up for his costly forays into the controversial boxer's mind, according to a filing in a court in the Los Angeles-area town of Santa Monica.

The Celebrity Justice television show said the fighter, famous for biting off part of Evander Holyfield's ear and for his many brushes with the law, began seeing Gibson following his release from a three-month jail stint for assault in 2000.

Gibson claims that he treated Tyson for a fee of 8,000 dollars a month and charged him an extra 6,000 for emergency cross-country visits.

The psychiatrist, who is based in Tempe in the western state of Arizona, entered Tyson's life at one of its many low points.

While in therapy, Tyson brawled with Lennox Lewis, threw glass ornaments at reporters in Havana, and was sued for divorce by his wife. The total amount owed by the boxer, who has served jail time for rape and assault over the years, came to 29,360 dollars.

Gibson claims that he was instrumental in getting the boxer back in the ring after Tyson was stripped of his licence for a year following his attack on Holyfield during their championship re-match in 1997.
