SANFORD — Police have announced a $500 reward for information leading to the arrest and indictment of the person responsible for the armed robbery of the convenience store called “88 High Street” Jan. 25.

The robber, whom police said displayed a small, silver handgun, took the cash drawer and contents, and also allegedly fired a shot at the clerk who followed him out of the store before he got into an SUV that sped away. The clerk was not injured.

While there have been a number of robberies in which weapons were displayed in Sanford and other southern Maine communities in recent years, this appears to the first firing of a weapon in concert with a robbery in recent memory.

The suspect is about 6 feet tall and weighs about 190 pounds, according to police. At the time of the robbery, he was wearing a black-and-red checkered flannel jacket and a gray ski mask.

Anyone with information is asked to call Sanford Police at 324-9170 and press 4.
