I asked the Seattle Police Department for more information on the incident and received the following reply. It is cut and pasted, unchanged from the SPD response below:
On Saturday evening at approximately 8:00 pm officers responded to reports of a man with a gun in the 200 block of NE 45th St. As officers were headed to the call, there were updates from other 911 callers stating that the same individual had been harassing tenants inside an apartment building, and walking into neighboring businesses threatening employees and customers. One of the witnesses stated that the man lifted his shirt and displayed what the witness believed was a black semi-automatic handgun.
Officers were interviewing the numerous witnesses and various locations in Wallingford when another update came in stating that the suspect had returned to his residence at the apartment building in the 200 Block of NE 45th. Officers attempted to convince the suspect to come out, but it was clear that he was becoming more and more agitated and was in crisis, based on the comments he was making. Believing he was armed, officers began evacuating the neighboring apartment units.
A police negotiator responded and attempted to establish a dialogue with the suspect, but they were unable to convince the suspect to exit his apartment.
A search warrant was written and was granted by a judge. SWAT officers responded to the scene to of the barricaded individual.
After a long period of attempting to negotiate with the suspect, SWAT used several “less lethal” devices (noise makers) to get the suspect’s attention. The suspect refused to exit. SWAT finally entered the apartment and took the man into custody.
The 38-year-old male was arrested and booked into the King County Jail for investigation of felony harassment. Officers searched the apartment per the warrant but did not locate any firearms. Detectives will continue to follow up on this incident.
Police activity has been ongoing in the area of 45th and Thackery since about 1am. The impacted area has covered multiple blocks. Buses and cars have been rerouted all evening. We will post more as we learn more.
