A suspect has been arrested in connection with a drug store robbery earlier this month that briefly shut down two Marietta schools, police announced.

A Marietta Police Department spokesman said a warrant charges Travis Bernard Allen, 28, with armed robbery, aggravated assault and kidnapping for his alleged role in the March 13 robbery of a Rite Aid store. The robbery caused lockdowns at Marietta High School and A.L. Burruss Elementary School.

Allen was arrested without incident in Decatur on Saturday and was being held in the DeKalb County jail pending a transfer to Cobb County, Detective Christopher Lindsey with Marietta police said.

Two men armed with a shotgun or a rifle and a handgun obtained an unknown amount of cash from the Marietta store. They forced a female shopper to the rear of the store, but she was able to fight off one of the suspects and flee.

A vehicle tag number allowed detectives to identify Allen as one of two suspects in the robbery, Lindsey said. Police are still searching for the second suspect, he said.

The individuals involved in the Marietta robbery are also suspected in a series of drug store robberies in Gwinnett, Douglas and DeKalb counties, as well as the town of Newnan, Lindsey said. Authorities in those counties as well as the U.S. Marshals Fugitive Task Force have been working together on those cases, he said.
