PORTLAND, Ore. -- A Safeway grocery store at Jantzen Beach in Portland was evacuated Friday evening after a 48-year-old man claimed to have a gun and locked himself in the manager's office with a woman, police said.

The man allegedly entered the store at about 5:30 p.m. and locked himself in the office with a woman who was with him, according to Chris Burley, spokesman for Portland police.

The man asked that the store be evacuated and it was, Burley said. Officers helped customers leave the store and then talked with the man over the phone.

The man allegedly made multiple demands and threatened that if the demands weren't met, police would have to shoot him, Burley said.

Officers said the man appeared to be in a mental health crisis. A gun was never found.

The man eventually agreed to leave the manager's office with the woman. Police said he was cooperative.

Officers said the woman appeared to have entered the office willingly.

The man was taken to a Portland hospital for a mental health evaluation, police said.

The man's name has not been released.
