The incident unfolded at about 1 a.m. when an officer responded to a 911 call about an armed robbery of a citizen in Fife. The caller was able to provide a description of the suspects' vehicle and a license plate number, said David Woods of the Fife police.
An officer then located the suspects' vehicle at Love's Travel Stop in Fife. The officer approached the vehicle and there was a violent struggle as the suspects tried to get away and flee the scene, Woods said.
The officer was dragged a short distance by the suspect's vehicle, and he opened fire at the suspects, but missed.
The suspects' vehicle then got away, heading south on I-5 as officers took off in hot pursuit. During the chase, it's believed that the suspects opened fire at the police following them about halfway between Fife and Tacoma, Woods said.
"We believe they fired on our officers - they saw muzzle flashes and the rear window breaking out of (the suspects') car," Woods said. "It shows they will do anything to get away from the police."
No officers or vehicles were hit by the gunfire.
Officers lost sight of the vehicle around 46th Street in Tacoma.
Police in the area are now looking for the vehicle, described as a dark colored Ford Expedition. Both suspects are considered to be armed and dangerous.
The officer who was dragged sustained cuts and scratches. He was checked out at a local hospital, then released.
