Officer injured in skirmish at SF’s downtown Westfield mall

Much of the downtown Westfield San Francisco Centre was closed Sunday evening after a fight broke out, injuring a police officer and prompting the arrest of a juvenile, authorities said.

Police did not immediately disclose the details of what happened, but dozens of officers remained outside the mall on Market and Fifth streets at 8 p.m., at least an hour after the incident. The mall’s Fifth Street side was shut down for the investigation.

The officer’s injuries were minor, authorities said. The name and age of the juvenile who was taken into custody were not disclosed.

The incident occurred after the Pride Parade, and many people were in the area at the time.
