Police in Pleasant Hill, Concord and Walnut Creek are dealing Sunday night with protesters and others associated with the death last week of George Floyd in Minneapolis, and are warning open businesses to close and people to stay away from commercial areas for fear of violence.

Pleasant Hill police Sunday night advised all open stores - primarily Target at Interstate Highway 680 and Chilpancingo Parkway and several grocery stores - to close as a precaution.

"We have people starting to move through Pleasant Hill, and as a precaution, we are advising all stores to shut-down. We are asking everyone to go home - store fronts, including grocery stores, will be closing-up as a safety measure," Pleasant Hill police said on their Facebook page.

People who may be protesters or vandals have been seen near Pleasant Hill's downtown district, as well as at the Crossroads shopping center across I-680 from the downtown. Crowds also have been seen at the Best Buy store a half-mile south of the Crossroads center, police said.

The Concord and Lafayette BART stations have been closed to what that transit agency describes as a "civil disturbances." There had been some vandalism and looting reported at the Sunvalley Mall in Concord, about a half-mile north of downtown Pleasant Hill, and police have responded to that area.

The City of Walnut Creek, in reaction to widespread vandalism and looting downtown, enacted a curfew that began at 6:30 p.m. Sunday. A young woman was shot in the arm at about that time along Locust Street downtown, apparently by a vandal.

Earlier in the day, there had been peaceful protests in Brentwood and Oakley.
