SEABROOK ISLAND -- Charleston County sheriff's deputies were using helicopters and tracking dogs to search for two people who robbed a bank here Tuesday afternoon.

About 3:30 p.m., two people, one armed with a handgun, walked into the BB&T branch office at 1900 Seabrook Island Road and demanded money, sheriff's Maj. John Clark said.

The tellers complied and gave the robbers an undetermined amount of cash. The robbers drove away from the bank in a white Ford Crown Victoria, which was later found abandoned on a dirt road not far from the bank, Clark said.

Deputies, assisted by officers from the Charleston Police Department, set up a perimeter around the abandoned car and were using tracking dogs to hunt for the robbers, Clark said.

The robbers were described as black. One was a man and the other was thought to be a female, Clark said.

The man was about 5 feet 9 inches tall, with a medium build. He was wearing a dark shirt that covered his face, a red hat and blue jeans. He was carrying a handgun, Clark said.

The other robber was 5 feet 7 to 5 feet 8 inches tall, with a medium build. She was wearing dark clothing.

No one in the bank was injured during the robbery, Clark said.

The bank is just outside the security gate to Seabrook Island, a gated community. The same bank was robbed by three men who entered the bank and fired shots inside in September 2006. No arrests were made in that case.
