New Bedford Police have arrested one person and are on the lookout for another in connection with an armed robbery at a North End Subway sandwich shop last night.

Police say two males robbed the Subway on Nauset St after 8pm Wednesday night, one of them armed with a possible rifle.

The masked robbers ran off with an undetermined amount of cash.

Within minutes, one of the suspects, a 14-year-old New Bedford teen was arrested, and the money was recovered.

Police are still searching for the other suspect and the rifle.

The at-large male is described as young and light-skinned, wearing a black hoodie and a black North Face backpack.

Anyone with information is asked to call detectives at 508-991-6300 ext 135.
