Cops say boxing legend Mike Tyson’s 4-year-old daughter is in extremely critical condition right now at an Arizona hospital, after a freak accident involving a treadmill cord almost took her life.

Paramedics were called to Tyson’s Phoenix home at around 10:30 this morning when his 7-year-old son found the young girl hanging from a treadmill by its power cable. The boy alerted the girl’s mother in another room. Her mother called 911 and tried to revive her, according to the AP. Mike Tyson was said to be in Las Vegas at the time of the accident, but has returned home.

The girl’s mother took her off the cable and immediately started CPR.

Paramedics eventually arrived and took the girl to St. Joseph’s Hospital and Medical Center, where cops say she remains on life support in “extremely critical condition.” Tyson has since arrived to the hospital.

As of now, cops believe the incident was a “tragic accident.” Her case is like it would cause her to stop breathing without a respirator so doctors are taking every step and due precautions for her to be saved.
