Dallas police are searching for the gunmen who started shooting at officers during a traffic stop in Oak Cliff Friday morning before getting away.
"It literally appears to look like a routine traffic stop. That's why its so shocking," said Dallas Police Maj. Robert Sherwin.
The traffic stop happened on the 500 block of South Llewellyn Avenue just after midnight.
The people in the car started shooting at police, who returned fire.
No officers were injured during the shootout.
"What I want to stress is that it appears that this an unprovoked attack on our officers," said Sherwin. "We don't know the reasons why this man opened fire but we're still finding out all the things we need to do to get this investigation going."
The suspects drove away and there was a short chase, but the police car broke down and the suspects got away.
Police released several photographs of the damaged police cruiser on Twitter. From the photos, it appeared that the car was shot at least four times.
At about 4 a.m. police found the suspects' vehicle, a late model Hyundai, on fire in the 2000 block of Mountain Lake Road, about three miles away from the initial traffic stop.
Police took photographs of the suspects' vehicle and searched for fingerprints and other evidence. There was heavy smoke damage to the interior of the vehicle.
"Obviously any investigation, where for unknown reasons, an armed suspect opens fire on two uniformed officers in a police car that citizens of this city should be concerned," said Sherwin.
