A courthouse in Washington state was locked down for several hours on Monday as authorities negotiated with and later arrested an armed man in the building's lobby, law enforcement officials said.

The standoff at the county courthouse in Everett, north of Seattle, began at around 12:30 p.m., The Herald reported. The man was taken into custody about three hours later, the Snohomish County Sheriff’s Office said. No one was hurt.

Selena Rios told the newspaper that she came to the courthouse with her 5-year-old child around 12:25 p.m. and that the armed man walked in right after them.
