A patient being taken by ambulance to the hospital hijacked the vehicle and led police on a chase before crashing, authorities said.

Police say the incident began at about 9:30 p.m. on Sunday when West Springfield emergency medical technicians were taking the man to Mercy Medical Center.

But the patient, identified by police as 49-year-old James Williams, allegedly began beating the EMTs, who jumped out of the vehicle.

Springfield Police Lt. Robert Strzempek says the patient then drove through the Peter Pan bus terminal hitting a bus and a parked car. The chase ended when the patient collided head-on with a car on Main Street. There were no serious injuries.

Williams faces a variety of charges including larceny of a motor vehicle, assault and battery with a dangerous weapon.
