Undefeated boxing champ Floyd Mayweather, Jr. has begun his 90-day prison sentence in Nevada.
The sports star surrendered to authorities in a Clark County courtroom on Friday afternoon (01Jun12) and was led away in handcuffs to start serving time for a domestic violence charge.
The count is the result of Mayweather, Jr.'s arrest in September, 2010, after his ex-girlfriend, Josie Harris, accused him of striking her "multiple times in the head with his fist" in front of their two children, who were aged nine and 10 at the time of the attack.
He was initially due to begin the three-month sentence in January (12), but appealed to a judge to delay the punishment until after his big money bout with Miguel Cotto last month (May12). He was given until Friday to turn himself in.
