Anchorage police say a suspect arrested in a downtown disturbance Tuesday morning, which temporarily closed a busy street, had made a threat to destroy a recently renovated local landmark.

Police spokesman MJ Thim said 32-year-old Kate Okpeaha was arrested after threatening to blow up the Anchorage Museum, which is unveiling a new wing this week on the east side of the building.

Thim said a call reporting the incident, along 6th Avenue near C Street, first came in at about 7:50 a.m.

Officers had tried to negotiate with the suspect, who allegedly threatened officers with a knife and refused to leave the area of the museum's truck dock. Thim said officers used pepper spray and a Taser to subdue the suspect, who was arrested on charges of assault and terroristic threatening.

An initial statement from police at about 8:30 a.m. said eastbound traffic along 6th was being diverted. The closure had ended by 9:45 a.m., according to an update.
