UPDATE: 10:30 p.m.

Anchorage Police fatally shot a man in the Sand Lake area Monday evening after he attacked a police K-9 with a sword, Chief Justin Doll said during a news conference.

APD says at 2:25 p.m., officers received a tip that an a man was brandishing a weapon at a home on the 1700-block of Wildberry Loop. While officers were en route, they received additional information that the suspect was under the influence of drugs, threatening suicide, and had pointed his gun at more than one person, according to police.

APD says when officers arrived, they saw the suspect standing outside a vehicle while holding a handgun. Police say he ignored officers' commands and walked up to the home where he lived and attempted to enter through the front door. When he was unable to do so, police say he fired his gun which broke a window next to the door. APD says the suspect then turned around, pointed his gun at responding officers, and fired a shot.

The suspect was able to get into the house using the broken window. Initially there were three other people inside; they exited the home without being injured, according to police.

The APD SWAT unit responded, along with negotiators, and APD says they attempted to communicate with the suspect, but he did not respond.

APD says at 6:35 p.m., chemical agents were deployed into the home.

"At that point, the suspect exited the residence through a rear window" said Chief Doll. "He appeared to be armed with a large sword, he approached our perimeter team which included a police K-9, he attacked the police K-9 with the sword and was shot by the swat officer who was in the perimeter position."

APD say the suspect was taken to the hospital where he was declared deceased shortly after 7PM.

The K-9 was taken to a pet hospital for treatment. Police says at this time the dog is expected to survive his wounds. No other officers were injured.

APD says in accordance with its policies, the state’s Office of Special Prosecutions (OSP) will review the officer’s use of force and determine whether or not it was justified. Once that has been completed, APD Internal Affairs will review the officer’s actions to confirm whether or not there was any violation of policy. The officer involved in the shooting will be placed on four days of administrative leave. His/her name will be released publicly 72 hours after the incident along with the name of the injured K9, police said.

The suspect’s identity will be released once next-of-kin notification has been done, police said.

Police are asking drivers to avoid the area and residents to stay indoors after shots were reported fired on Strawberry Road and Wildberry Loop.

Anchorage Police Department said that the incident began approximately at 2:25 p.m. when officers responded to reports of a suspicious person with a gun.

After officers located the man, he fired shots at multiple officers, but no one was injured.

Police say that the suspect has since barricaded himself inside a residence in the area of Strawberry Road and Wildberry Loop and refuses to come out.

APD says traffic is being shut down at the Strawberry Road exit from Minnesota. Drivers are asked to find alternate routes.

SWAT, Patrol Division, and Crisis Negotiators are responding, and closures of Strawberry Road and Wildberry Loop remain in effect.

Police say that they could use "less lethal tools and tactics to bring this situation safely to a close," including drones or chemicals. They are thus advising nearby citizens with respiratory sensitivities to remain inside.

Citizens are asked not to post any photos or images on social media of the situation until it is resolved.
