CONCORD -- Police are asking for the public's help in finding three men who they say robbed a jewelry section at Macy's at the Sunvalley Mall late Wednesday.

The heist occurred around 9:05 p.m., when three men walked into the store with jackets and hoods over their heads and went to the jewelry counter, Concord police Lt. Darrell Graham said. One of the men jumped over counter and broke open jewelry cases and the three then stole several pieces of jewelry. The amount of jewelry taken and its value were not known, police said.

Descriptions of the three men were not available, Graham said. One of them carried a handgun but no shots were fired, Graham said.

The three men ran outside and drove away in a tan Toyota Camry and headed north on Contra Costa Boulevard after the robbery, Graham said. The car later was found in neighboring Pleasant Hill at the intersection of Ruth Drive and Baylor Lane, less than a half-mile from the mall, Graham said.

Police assume the suspects got into another car and fled, but the make and model of that car are not known, Graham said.

Anyone with information is asked to call the Concord Police Department at (925) 671-3030. Those wishing to remain anonymous can call the Concord Police Department Tip-line at (925) 603-5836.
