BREA (CBSLA.com) — Police asked for the public’s help Thursday to identify a man who robbed a jewelry store inside the Brea Mall.

The robbery happened at Kevin Jewelers last Tuesday at about 6:45 p.m. when a man asked a clerk to look at diamond solitaire rings, Brea police spokesman Lt. Darrin Devereux said.

When the clerk showed the man a ring, he lifted his shirt and took a silver handgun from his waist band and demanded the ring, plus four more rings from a display case, Devereux said. The suspect fled the store with the rings, and left in a white, mid-size sedan with distinctive taillights.

The value of the stolen jewelery was not available, Devereux said.

It’s is the latest crime against a Kevin Jewelers store in Southern California since last September. Kevin Jewelers locations inside shopping malls have been robbed in a similar fashion – with the robber asking to see rings, then taking out a gun and fleeing with several more rings – in Riverside and Northridge.

The suspect in the Brea robbery was described as a white or Hispanic man, about 6 feet tall, 16 pounds, about 65 to 70 years old, possibly walking with a limp. He wore eyeglasses and a Vietnam Veterans baseball cap.

He bears a resemblance to the suspect in the Northridge robbery, and Brea detectives are working with LAPD detectives on these cases, Devereux said.

Kevin Jewelers is offering a $10,000 reward for information leading to the arrest and conviction of this suspect.
