Cobb County police are investigating the Thursday night robbery of a Dunkin' Donuts in Kennesaw.

The suspect entered the restaurant in the 4300 block of Bells Ferry Road about 9 p.m. Thursday and asked the cashier if she was alone, Cobb police spokesman Joseph Hernandez said.

"When the cashier stated she was not, the male asked her to summon her coworker to the counter," Hernandez said. "The male then approached both employees in a threatening manner and demanded all of the money from the cash register."

Hernandez said the robber left on foot with an undisclosed amount of money from the register. While he never showed a weapon, the employees believed he was armed with a handgun, Hernandez said.

The robber was described as white, 45 to 50 years old, 5 feet, 8 inches to 5 feet, 10 inches tall and having dark complexion and dark hair. He was last seen wearing a denim jacket, orange t-shirt and baggy jeans.
