PHOENIX (AP) - Police say the 4-year-old daughter of boxer Mike Tyson died a day after her neck accidentally was caught in a treadmill cord while playing at home.

Phoenix police spokesman Andy Hill said Exodus Tyson was pronounced dead in a hospital just before noon. Police are calling it a "tragic accident."

Police say the girl was playing on the treadmill Monday when her head apparently slipped inside a cord hanging under the console. Exodus' 7-year-old brother found her and alerted his mother.

Former heavyweight champion Tyson was in Las Vegas at the time of the accident and flew to Phoenix on Monday.
