The Target in San Francisco's Metreon shopping center was evacuated late Thursday after someone released pepper spray in a store bathroom, officials said.

Officers responded at 7:10 p.m. to the store at 789 Mission St. on a report of employees and customers in the big-box retailer experiencing physical symptoms because of an unknown substance released in the store, according to San Francisco Police Department spokesperson Sgt. Kathryn Winters.

Before officers arrived, paramedics were already at the store assessing people with symptoms, officials said.

The incident comes just a day after someone sprayed bear mace in an Antioch Hobby Lobby, causing a hazmat situation that led to at least 69 people getting medical evaluations or treatment.
