A brawl broke out in a Long Island Chuck E. Cheese earlier this week, but it wasn’t between a group of kids…it was an adult fight.

Several people were involved in the brawl, and it was all caught on camera as an onlooker recorded from their phone. Chaos ensued as children jumped in to try and stop the fight, and one woman was actually engaged in combat while holding a baby. The store’s manager said he couldn’t comment on the incident as police are investigating, but he can be seen in the video trying to pull the women apart. It’s unclear what started the fight.

The altercation broke out just as people were singing “Happy Birthday” at the party.

“It’s a disgrace. It shouldn’t happen. You should be able to control yourself enough to deal with your issues later,” an onlooker said.

“This is for kids, it’s supposed to be wholesome, it’s supposed to be fun, and this destroys all that,” another witness said.
