PHOENIX – The four year old daughter of Mike Tyson is on life support at an Arizona hospital the result of a tragic accident on a treadmill.

It all happened at a family home in the Phoenix area on Monday. Police say the girl’s seven year old brother found her on a treadmill with the cord tangled around her neck.

Police say it appears she was playing on the treadmill and somehow got stuck in a looped cord off the treadmill.

Her mother was apparently in another room at the time. Mike Tyson was out of town. The little girl is currently listed in extremely critical condition.
