Boxer Mike Tyson's 4-year-old daughter was on life support on Monday after she was found with her neck on a treadmill cable, police announced.
Police Sgt. Andy Hill said that the "tragic accident" happened Monday morning at Tyson's Phoenix home.
Hill said that the girl's mother was cleaning when she sent her 7-year-old son to find her. The boy found his sister in distress and got his mother, who found the girl on a treadmill with her neck on a cable attached to the exercise machine.
The girl's mother called 911 and began trying to revive her. Officers and fire officials performed CPR on the girl while taking her to the hospital.
