Novato police on Monday released surveillance video as they continued searching for three suspects involved in a smash-and-grab jewelry robbery at a Costco store Sunday morning.
About 10:10 a.m., officers were dispatched to the Costco at Vintage Oaks on reports of a robbery. Three suspects entered the store wearing surgical masks and proceeded directly to the jewelry display cases, police said.
The suspects used a hammer to smash the glass cases and stole numerous pieces of jewelry. They ran out of the store to a waiting vehicle and fled the area before officers arrived, police said.
"Went straight to the jewelry display case, smashed it open, took an undetermined amount of jewelry," Novato police Sgt. Alan Bates said. "We’re going to do what we can do to identify the suspects. We’ll work with outside agencies that have experienced the same kind of incident, and see if we can collaborate."
No weapons were seen, and no one was injured during the robbery, police said. The suspects and suspect vehicle were not found.
Witnesses described the suspects as African American men, possibly in their 20s, police said. The suspect vehicle was described as a dark-colored, four-door sedan with paper dealer plates.
Police are looking at surveillance video from the front entrance of the store to see if it will help identify the suspects.
Other Bay Area Costco stores have been targeted in similar robberies over the past two months. In May, a Danville store was hit twice. One suspect was arrested in the first robbery. The second happened about a week later, and the suspects made off with high-priced watches.
Last month, the Foster City Costco also was robbed. In all the robberies, the suspects wore masks.
Police asked for the public's help in locating the vehicle and the suspects in Sunday's heist. Anyone with information should call 415-897-4361.
