Deputies are looking for clues in a weekend robbery in which a man held an employee at gunpoint inside a Mexican restaurant on James Island and stole cash-carrying bags, the Charleston County Sheriff's Office said Monday.

Authorities were called at 12:14 a.m. Sunday to Zia Taqueria at 1956A Maybank Highway.

An employee at the back of the building told deputies that someone had gotten inside through an unlocked door leading to a hallway and other adjoining business, the Sheriff's Office said in a statement.

The robber pointed a silver and black handgun at the worker and demanded money, the agency said. The robber reached into a desk, then ran away with pouches used to transport cash.

How much money was in the bags wasn't known, the Sheriff's Office said.

Nobody was hurt.

During an ensuing search, police dogs, a helicopter and deputies could not find any suspects.

The robber was described as a light-skinned black man who was about 6-feet-1 and 180 pounds, according to the Sheriff's Office. During the robbery, he wore a dark hooded sweatshirt and dark pants.

Anyone with information about the robbery is asked to call the Sheriff's Office at 843-202-1700 or Crime Stoppers at 843-554-1111.
