A Philadelphia officer and three other people were hospitalized after a patrol car collided with an SUV

Four people, including a Philadelphia police officer, were hospitalized overnight after the officer's marked vehicle collided with an SUV at the intersection of 5th and Callowhill streets.

According to Chief Inspector Scott Small, the 9th District officer was traveling alone to assist with a vehicle investigation near 6th and Market streets when his patrol car and SUV collided around 12:30 p.m

The 34-year-old officer was taken to Jefferson Hospital for treatment of his head and facial injuries, although Small said he was able to walk and talk again after the accident.

Of the four people in the SUV, three people — two teenage males and a woman in her 20s — were also taken to Jefferson. According to police, a fourth male person in the car was uninjured.

Because the damage to both the police vehicle and SUV was so extensive, firefighters had to cut the officer out of his car, according to Small. “The civilian vehicle with the three injured occupants also had to be cut out of the vehicle by the fire department using life-threatening claws,” he said.

Despite the severe damage, Small said the officer and three civilians were considered stable when they went to the hospital.

Small said investigators are not sure whether the officer activated his lights and sirens before the crash and are still working to determine who had red and green lights at the time of the crash.

He added that police do not know whether drugs, alcohol or speed played a role in the crash or whether the driver, who was among the injured, was impaired in any way.
