According to police, a call came in around 8:15 p.m. of an attempted robbery at a store located at 117 Berlin Road.
Authorities say a short, skinny man entered the store dressed in blue jeans and a hooded sweatshirt while wearing a face mask. He then allegedly demanded money from the cash register, but the clerk refused to give it to him.
Officials say the clerk then chased the suspect out of the store.
The suspect entered a gold-colored older four door vehicle and fled the scene onto Interstate 91 Northbound.
