Donald Outlaw, 28, of no fixed address, was arrested by U.S. Marshals in High Point, N.C., Lt. Thomas Matera said.
“We want to thank the community for coming forward with information," Matera said. He said forensic evidence also played a role in the investigation and arrest.
The robbery occurred at 11:10 a.m. at the Gold Rush Pawn Shop on Connecticut Avenue, and police asked for the public's help in finding the thieves.
At the time Norwalk Police identified two suspects: a black man with long dread locks and a Hispanic man who displayed the handgun. Matera said the investigation was ongoing.
