A series of armed robberies in Charleston Wednesday night could be linked, investigators say.

A man robbed a Circle K at gunpoint about midnight Thursday, then sped away in a tan truck, Charleston County Sheriff’s Office spokesman Capt. Mike Stanley said.

The suspect forced an employee at the 2407 Ashley River Road store to empty two registers and lay on the floor before he fled the scene.

The employee described the suspect as a black male wearing long dark clothing, a knitted hat, white gloves and a white scarf that covered his face, a report stated.

Charleston police responded to a Li’l Cricket on Ashley River Road earlier in the night regarding the attempted robbery of a Murphy USA gas station at 3969 West Ashley Circle.

A woman closed Murphy USA then quickly got in her car when a man with a similar description exited a gold Chevy Tahoe and approached her, a report stated.

The woman noticed a gun in the man’s hand as he pulled on the handle of her driver’s side passenger door. She drove away to wait for police.

A man tried to enter a Kangaroo gas station at Main Road and Savannah Highway about thirty minutes earlier, a report stated.

A store employee said the man sped off in a gold Chevy Tahoe when he couldn’t get into the store.

Investigators are still searching for a suspect.
