Police are investigating reports of windows at three Norwalk businesses that were shattered with a pellet gun.

Authorities say the windows began to be shot out Monday at about 3:45 p.m. At a Dunkin' Donuts on Westport Avenue, a woman was sitting just inside a window when it was shot out. Surveillance video shows the woman quickly jump out of her chair and police arriving moments later.

Norwalk police say within the next 45 minutes, they received three more reports of shot-out windows. Officers say the two other pellet gun shootings happened at a Midas on Main Street and World of Beverages on Main Avenue.
