STAMFORD — A city woman was charged with intentionally backing her car into another vehicle while her 4-year-old son was a passenger in the same vehicle, police said.

On Friday at about 2:40 p.m., police were called to an escalating argument following a traffic accident in a parking lot on Austin Avenue, Sgt. Sean McGowan said.

When police got there, they found two women were in the midst of a dispute that ended with one car being rammed into another.

One woman told police that less than an hour before, she was driving north on Washington Boulevard and approaching Travis Avenue when a Nissan Altima pulled in front of her and slammed hard on the brakes.

The woman said she didn’t rear-end the Nissan. Instead, she drove around it and gave her passenger a drive home, McGowan said. She added that the woman driving the Nissan looked like the same woman who had been sending her boyfriend Snapchat messages for the past three weeks.

The woman returned to see if she could find the car and confirm who she thought was behind the wheel. In the driveway behind 41 Austin Ave. she found the woman, Lara Agatstein, 23, with the Nissan.

After an argument, the woman told police Agatstein jumped into her Nissan and “violently” reversed into her front bumper. The woman got into her car and Agatstein pulled the car forward before reversing it again and hitting it for a second time — all while her young son was the rear passenger seat, McGowan said.

Police quickly found Agatstein, who appeared highly agitated and refused to answer any questions. She was charged with risk of injury to a child, reckless endangerment and breach of peace and held her in lieu of a $5,000 court-appearance bond.
