WEST HOLLYWOOD, Calif. (KABC) -- A search is underway for two thieves who targeted a West Hollywood jewelry store and made off with $400,000 worth of merchandise.The heist took place on June 23 around 5 a.m. at Gina Amir Atelier at 509 North Robertson Boulevard, according to the Los Angeles County Sheriff's Department.One of the suspects smashed the glass front door using a spark plug, detectives said. The man then kicked open a door separating the jewelry display area from the back offices.Once inside the office area, the suspect removed jewelry from a safe. He then ran from the building to an awaiting vehicle, driven by an accomplice.A sheriff's press release stated that the safe was unsecured, but the store's operation manager told Eyewitness News that the safe was indeed secure, and the suspect broke it open.The getaway car was described as a newer model, silver or dark colored four-door sedan.The stolen goods include diamonds, gems and other jewelry.Investigators said it remains unclear this was a targeted job."It's hard to say. It could be something as maybe they came into the store one day and saw the staff members go into this particular room. At that point, we don't know. This is still an investigation," said LASD Lt. William Nash.The first suspect was described as a black or Hispanic male, approximately 6 feet tall, between 25 and 35 years old, weighing around 210 pounds. A description of the getaway car driver was not available.If you have any information about this crime, you're urged to contact Detective Luevano with the LASD's West Hollywood station at (310) 358-4055.
