By Lt. Mike Pistello, San Ramon Police Department

On Monday, September 22, 2025, at 1:50 p.m., San Ramon Police Department personnel responded to Heller Jewelers, located at 6000 Bollinger Canyon Road, for a take-over style armed robbery. Approximately 20 masked individuals entered the store and began smashing display cases, taking numerous items. Several suspects were armed with handguns, and at least one suspect fired rounds through the front entrance. Fortunately, no one was injured, and there is no ongoing danger to the public.

The suspects fled the scene in awaiting cars they had staged in the City Center valet parking area. San Ramon Police Officers pursued some of the involved vehicles but terminated due to the inherent danger to the public and because of air support was overhead and available to continue tracking the suspect vehicle.

Law Enforcement air support tracked the suspects through Contra Costa and into Alameda County. Several suspects were detained at two locations in Oakland and a second location in Dublin.

See surveillance camera and drone video footage included in the NBC Bay Area which reported police said the thieves “helped themselves to more than $1 million of fine jewelry.”

San Ramon Detectives will tirelessly continue their investigation into this incident and ask anyone who may have witnessed the robbery to contact Detective Corporal Kevin Tjahjadi at (925) 733-7316.

The San Ramon Police Department would like to thank the Alameda County Sheriff’s Office and the Oakland Police Department for their assistance. This incident is still under active investigation, and we will not be releasing any additional information until it is appropriate, as it may compromise the ongoing investigative efforts.
