A Belmont woman faces multiple charges, including assault and battery with a dangerous weapon, after allegedly throwing a feces-filled bag through a car window and striking the face of a man she claims was speeding.

According to a police report, an officer on Oct. 1 met with a Belmont man who stated he was driving down Stone Road the previous morning when an object came through his open window and hit him in the face. He soon realized the projectile was “a flying bag of dog feces that splattered across his face, and the remaining matter soiled the front of the car,” the report said.

The day before, on Sept. 30, an officer was dispatched to Stone Road to take a report from a woman about a speeding complaint. The woman reported she was walking her dog down Stone Road and threw a bag at a dark-colored sedan that was allegedly speeding down Stone Road, almost hitting a person on a bicycle.

The woman told police she ran to hid in a neighboring yard after throwing the bag, which she admitted was filled with feces, because the vehicle remained in the area.

Police were unable to locate the vehicle after the incident, and have not yet determined whether the man was speeding, according to Lt. Rick Santangelo, a spokesman for the department.

“Even if he was, that person could have lost control of the vehicle and there could have been a tragedy,” Santangelo said, adding there are other, better ways to handle speeding situations. “People need to control their immediate impulse to take action in a situation like this. The best course of action in a situation like that would be to get the license plate number and call police with a description of the vehicle and direction of travel.”

The woman is being charged with assault and battery with a dangerous weapon, vandalism to property and disorderly conduct, Santangelo said.
