A 19-year-old was one of two Lithonia teenagers arrested in connection with armed robberies at Dollar General stores, police said.

The other teenager arrested was 16 and his name won’t be released, Newton County Sheriff’s Office spokesman Jeff Alexander said.

Tolek Raphelle Johnson and the 16-year-old were stopped by Covington police on Aug. 3 when their car matched the description given by witnesses.

Witnesses told the 911 operator that two men in masks fled the Dollar General on Highway 142 North in Oxford in a silver car with one taillight out, Alexander said.

A search warrant was issued for the car, in which a gun, masks and clothing tied the teenagers to other armed robberies, Alexander said.

Johnson was charged in the Oxford robbery and in the July 25 armed robbery at the Dollar General on Highway 81. Authorities also charged him in the July 24 armed robbery at the Dollar General on Highway 20.
