A New York Jets fan caught on video punching a woman in the face after the team’s victory over the New England Patriots Sunday has sparked an investigation from New Jersey State Police.

It is not clear how the altercation began, but the woman in the video was wearing a Patriots T-shirt, MyFoxNY.com reports.

“We are aware of the situation and we do not tolerate that behavior,” a Jets spokesman said, according to the New York Daily News. “Parties involved were detained and this matter is now in the hands of the New Jersey State Police.”

In the video, the woman is seen walking toward the man at Met Life Stadium and she tries to push him before the man responds with a punch. The alleged attacker was wearing a Wayne Chrebet jersey (No. 80) and camouflage pants, according to the News.

Another man wearing a Patriots shirt then moves in to take a few swipes as the woman backs away. Eventually a crowd separates the two groups.

There were no serious injuries reported in the fight, MyFoxNY.com reports.

The Jets won the game 30-27 in overtime. The team, led by rookie quarterback Geno Smith, improved to 4-3 on the season, breaking a five-game losing streak to the Patriots.
