Battle Creek — Authorities say three people died when an ambulance carrying a heart patient crashed into a vehicle near a hospital in Battle Creek.

According to police, the accident happened around 1 a.m. Tuesday about three blocks from Bronson Battle Creek Hospital. A vehicle apparently ran a red light while the oncoming ambulance had its emergency lights and siren activated.

Police say a female driver and male passenger were killed when the vehicle collided with the ambulance. The patient was transferred to another ambulance and taken to the hospital, where he or she died shortly after arriving.

A Battle Creek firefighter in the ambulance also was injured.

Police believe alcohol and speed may have been factors in the fatal crash. An investigation is ongoing.
