A shocking end to a road rage incident was caught on video this week. As you'll see from the video below obtained by WCVB-Boston, a woman is pushed to the ground by a man. This happened Sunday on Amherst Street in Nashua.

Jennifer Needham, who captured the video was a passenger in a nearby car. Needham told reporters that just before she started recording, the man was at the woman’s car window and walked away. Her video begins as the woman gets out of her car and approaches his. Needham admits she has no idea what led up to what she saw.

Police said this all could have been avoided.

“You don't know who you're dealing with,” said Lt. Carlos Camacho, of Nashua police. “You don't know what people are going through. It's better to give us a call, let us talk to everybody involved, and try to find out what happened.”

Police in Nashua said they've spoken to several witnesses and both parties involved, and the incident remains under investigation.
