A man armed with a handgun robbed a Town of Brookfield Subway sandwich shop Wednesday night and escaped, police said Thursday.

At about 10 p.m., police said, the robber, wearing all black clothing, walked in to the shop at 19555 Blue Mound Rd., went up to the counter and pulled up his sweatshirt to show a handgun in his pants waist.

He demanded cash from frightened employees and as soon as it was handed over, he left. The restaurant staff locked the doors and last saw the robber walking toward the nearby George Webb diner. No vehicle was seen, and no witnesses outside the Subway saw the man.

Town of Brookfield police said they have video evidence that is being followed up, but so far no suspect.

The robber was described as white, 25 to 35 years old, 5-feet-6-inches tall, weighing 140 to 150 pounds, and at the time wearing black jeans, a black sweatshirt and a black knit cap.
