The department is calling in additional officers and reserves and some stores may consider closing early or taking other precautions, police said.

Brett Barrette is one of the managers of P.F. Chang’s restaurant across from the Nordstrom store. He watched as the bedlam unfolded.

“I probably saw 50-80 people in like ski masks with crowbars, a bunch of weapons,” he said. “They were looting the Nordstrom.”

“There was a mob of people,” he continued. “The police were flying in. It was like a scene out of a movie. It was insane.”

Barrette also worried about the safety of the diners in his restaurant. Many crowded around the windows to watch the looters flee.

“I had to start locking the front door,” he said. “Locking the back door. You never know, they could come right in here. It was crazy … All the guests inside were getting concerned. It was a scary scene for a moment.”
