Concord, CA — Seven people were arrested after an alleged smash-and-grab burglary at Sunvalley Shopping Center before dawn on Sunday, October 5. Concord Police say mall security reported a break-in at about 3:52 a.m., and officers arriving moments later saw suspects running out of the building.
According to police, four suspects jumped into a getaway car and led officers on a short pursuit that ended in a crash nearby. The driver ran but was found hiding in bushes and taken into custody; the three passengers were arrested at the scene of the crash. Three additional suspects who stayed at the mall were also detained. No injuries were reported in the burglary or the collision.
One of the suspects located at the mall was carrying a firearm that had been modified to function as an assault weapon, police said.

Six of the seven suspects are male juveniles from San Pablo and Richmond and were booked into Contra Costa County Juvenile Hall. The seventh suspect, identified as 18-year-old Marcos Ramirez-Castro of Richmond, was booked into the Martinez Detention Facility. Police said there are no outstanding suspects.
Charges and what comes next
Concord Police said the group faces multiple charges tied to the burglary and the pursuit. Formal charging decisions will come from the Contra Costa County District Attorney’s Office.
Recent context
The arrest comes amid heightened regional concern about organized retail theft, including last week’s high-profile smash-and-grab at Heller Jewelers in San Ramon, where police have since announced multiple arrests.
While separate incidents, both cases have intensified calls for prevention and swift accountability across East Bay shopping centers.
