The Portland Police Bureau identified the officer as Laurent Bonczijk, who has spent seven years with the bureau.

Police responded to a “premise check” at a cluster of unoccupied, newly constructed condos adjacent to Sellwood Pool shortly before 2:30 p.m., said Portland police Lt. Tina Jones.

“Officers were checking this premises and they encountered a subject,” Jones said, “and during that encounter, one officer discharged their firearm.”

People at Sellwood Park said they heard what sounded like gunfire.

The officer then retreated, Jones said, and called for additional resources. The Portland Police Bureau sent dozens of officers — including the Special Emergency Reaction Team, Crisis Negotiation Team and Chief Chuck Lovell — to the home and ordered nearby residents to shelter in place.

Jones said police then deployed a robot to make contact with the subject and eventually took him into custody around 5:30 p.m.

Police did not confirm whether the person taken into custody was armed at all.
