A witness tells FOX5 that a confrontation ensued around 3:30 a.m. outside the emergency room at Mercy Hospital after the man tried to get a friend admitted into the hospital emergency room.
Officers say the man used an oxygen tank to shatter the ambulance windshield. He also broke off the passenger-side mirror and broke one of the rear windows. The man also tried hitting staff members with the tank, police said.
When officers arrived, they used a stun gun to subdue him. He was taken to a different hospital for treatment.
No further details were released.
