Ridgefield police are investigating an armed robbery at the Subway on Ethan Allen Highway in Branchville that took place Sunday, May 20, at 7:13 p.m. Police say a male suspect entered the restaurant across from the Branchville train station and took $342 from the register after brandishing a knife. The suspect appeared to be acting alone, police told The Press, and remains at large after fleeing the scene on foot. Nobody was hurt during the incident, police said. \u00a0 A phone call to the Subway location on Tuesday, May 22, requesting comment on the robbery went unanswered. Police say the suspect was spotted on the sandwich shop\u2019s video surveillance system. According to Capt. Jeff Kreitz, the last armed robbery in Ridgefield was in October 2015, when \u201can individual allegedly displayed a knife after being confronted by loss prevention at Kohl's department store in regard to a larceny,\u201d Kreitz said. Before that, in January 2014, a man walked into First Niagara Bank on Danbury Road and demanded cash. That person threatened employees by saying he had a gun. He fled the scene with another man who acted as the getaway driver. That incident resulted in the arrest of two men in connection with the robbery.
