Photos of a man wearing a Ku Klux Klan hood while shopping Saturday prompted a harsh rebuke from local leaders in San Diego County, and police now say they’re looking into the unsettling imagery.

The incident took place one day after health officials in the county ordered residents to wear face coverings in public to stymie the spread of covid-19. Tiam Tellez — one of several shoppers who captured photos of the hooded man at a Vons supermarket in Santee, Calif., and posted them on social media — wrote on Facebook that several store employees repeatedly told the man to take off the hood or leave.

Melissa Hill, a spokesperson for Vons, confirmed Tellez’s account and called the incident “alarming." She said the unnamed customer ignored staff requests to remove the hood until he reached the checkout area. At that point, the man removed the hood and purchased his groceries before leaving, according to the Los Angeles Times.
