The officer was expected to survive and was undergoing emergency surgery, department spokeswoman Jennifer Castro said.
The wounded officer and another officer who responded exchanged gunfire with the man, who was killed.
The shooting happened before 5 a.m. in downtown Anchorage as the officer was responding to reports of a theft suspect in the area on foot.
“The officer was pulling his patrol vehicle over and a man brandished a gun and started firing at the officer,” Castro says in an email to The Associated Press.
Additional officers arrived and provided first aid to both the officer and the suspect, who was declared dead, Castro said. Police haven’t released the shooter’s name.
Per department policy, the names of the two officers who fired their weapons will not be released for three days. Both the department and the state will conduct reviews to determine if the use of force was within department guidelines and justified.
Castro says the department will hold a news conference later Saturday morning to provide updates.
It’s the second shooting involving Alaska officers in the past month.
Sgt. Allen Brandt, an 11-year veteran of the Fairbanks Police Department, was shot Oct. 16. He died Oct. 28 in Anchorage of complications during surgery.
Brandt was attacked as he responded to calls of a shooting in a neighborhood east of downtown Fairbanks. Video from his dashboard camera showed his car slowing to a stop as Anthony Jenkins-Alexie, 29, approached on foot on the sidewalk.
The video showed Jenkins-Alexie, armed with a handgun, dashing in front of the car. Prosecutors say Jenkins-Alexie shot Brandt as Brandt tried to take cover behind his patrol car. He was hit six times. Jenkins-Alexie is charged with first- and second-degree murder and other counts.
