The shot shattered the back window. One of the medics was struck with shards of flying glass.
It happened while medics were responding to a call at 8 p.m. Tuesday night, racing down a road in Bellport, Long Island.
None of them heard the shot, but the back window shattered and glass struck one of the medics in the back.
Medics say shootings here are rare but not unheard-of.
Detectives examined the ambulance Wednesday morning, but the projectile whatever it was not recovered.
Investigators say the shot was most likely a high-velocity metal pellet fired at the ambulance from a bb gun.
