One bank was robbed Saturday and an attempted robbery happened at another nearby bank west of the Ashley, authorities said.

The same man is suspected in both crimes. He was described as a black male, 5 feet 8 inches to 5 feet 10 inches tall and weighing 160 pounds, the Charleston County Sheriff's Office said.

In the first incident, the Wachovia Bank at 1305 Sam Rittenberg Boulevard was robbed at about 11:50 a.m. Saturday. The suspect was wearing a white T-shirt and baggy pants. He handed the teller a note demanding money. He never brandished a firearm but implied he was armed, Charleston police said.

The suspect in the Wachovia robbery was handed an undisclosed amount of money that included a dye pack, which exploded and was recovered in the parking lot. The suspect should have pink or red dye on him and the money, the Sheriff's Office said.

An attempted robbery occurred at the Bank of America at 1806 Sam Rittenberg Boulevard about 30 minutes after the Wachovia robbery. The suspect did not get away with any cash. The Sheriff's Office said he was wearing a navy blue T-shirt, was clean-shaven and had close-cropped hair.

No one was reported injured at either bank. There was no description of a vehicle used in the robberies.

The robbery and attempted robbery on Saturday happened on the heels of the robbery of a Bank of America branch at 540 Folly Road late Friday afternoon. In that robbery, a man jumped over the counter and grabbed money from the cash drawers.

That man was described as either white or a very fair-skinned black man. He was between 5 feet 7 inches tall and 5 feet 10 inches tall and weighs between 170 and 190 pounds. He was wearing a white T-shirt, dark jeans, work boots, a dark bandanna around his face and a dark New York Yankees skull cap, officials said.

No one was injured in the 6 p.m. Friday robbery and only bank employees were in the building.

Anyone with information should call Crime Stoppers at 554-1111 or Charleston Police at 577-7434.
