The suspect was arrested “without incident,” the Bothell Police Department said around 3:30 a.m. Pacific Time.
He was located “hiding on a rooftop” close to where the shootings took place.
Police officials said a black male wearing a grey tank top and baggy sweatpants was pursued by two officers after a traffic stop around 9:40 p.m. on Monday. The suspect struck a man riding a scooter before slamming into a median.
When other officers arrived on the scene, they found one officer dead and another wounded.
It wasn’t clear whether the suspect or officers fired first.
The suspect fled on foot with a handgun visible.
Bothell police Capt. Mike Johnson told reporters that the man was “armed and dangerous.”
No Bothell Police Department officer had been fatally shot for over 25 years, Johnson said.
“It’s going to be a troubling time for our department and our profession,” he said. “This is uncharted territory for us. This is going to be a rough couple days for our organization,” Johnson said.
Bothell is a city in the Seattle metropolitan area with a population around 47,000.
The second officer who was injured was released from the hospital, Q13 reported. The pedestrian struck by the suspect was still in the hospital.
Bothell Councilman Mason Thompson said in a statement that he was “heartbroken” about what happened, adding, “My prayers are with the officers who have been shot and their families.”
