An elderly man was fatally injured Saturday when the ambulance in which he was being transported collided head-on with another vehicle in Pasadena, authorities said.

The crash was reported just after 4 p.m. on Fair Oaks Avenue, just south of Hammond Street, according to Lt. Jesse Carrillo of the Pasadena Police Department.
An ambulance operated by a private company was taking a man in his 70s to a non-emergency doctor’s appointment when the vehicle was involved in a collision with a four-door Jaguar sedan, the lieutenant said.
The ambulance’s lights and sirens apparently were not turned on at the time, police said.
The patient suffered a head wound was transported from the crash site to a hospital, where he was pronounced dead, Carrillo said. His name was not immediately released.
The driver of the Jaguar, a woman in her 60s, was hospitalized in stable condition after suffering a possible fracture to her foot, according to police.
The driver of the ambulance and a co-worker were also taken to a medical center in stable condition, Carrillo said. The nature of their injuries was unclear.
News video from the scene showed significant damage to the Lifeline ambulance and the Jaguar.
It was not immediately known whether a Lifeline employee was in the back of the vehicle at the time of the collision.
The cause of the incident is under investigation.
