The 4-year-old daughter of boxing legend Mike Tyson has passed away one day after she accidentially hung herself with a treadmill cord while playing at home.

“I was just advised by investigators that Exodus Tyson was pronounced deceased at 11:45 AM today at the hospital. Our sympathies go out to the family,” a rep for the Phoenix Police Department said in statement released this afternoon.

Police believe the little girl had been playing on the treadmill when her head slipped inside a cord hanging under the console. Exodus’ 7-year-old brother found her unresponsive and alerted their mother, who immediately contacted paramedics.

Tyson — a former heavyweight boxing champion — was in Las Vegas at the time of the accident and flew to Phoenix after learning his daughter had been hospitalized.

Authorities have ruled the child’s death a “tragic accident.”

Very sad…Rest In Peace, Exodus….
