PHOENIX (AP) — The 4-year-old daughter of boxer Mike Tyson died at a hospital Tuesday, a day after her neck apparently got caught in a treadmill cord at her Phoenix home, police said.

Exodus Tyson was pronounced dead just before noon, police Sgt. Andy Hill said. She had been on life support and police have said their investigation showed her injury on Monday was a ‘‘tragic accident.’’

‘‘There are no words to describe the tragic loss of our beloved Exodus,’’ the family said in a statement. ‘‘We ask you now to please respect our need at this very difficult time for privacy to grieve and try to help each other heal.’’

Police said Exodus either slipped or put her head in the loop of a cord hanging under the console. Her 7-year-old brother found her and told their mother. She took Exodus off the cord, called 911 and tried to revive her.

Responding officers and firefighters performed CPR as they took the girl to the hospital.

Former heavyweight champion Tyson was in Las Vegas at the time of the accident and flew Monday to Phoenix, where he was seen entering the hospital.
