One man died and three more were arrested after a brawl between two wedding parties at a suburban Philadelphia hotel captured on video by a 15-year-old boy celebrating his birthday.

"They just started punching each other and hitting each other," Max Schultz told KYW-TV. "The police came in and started clubbing people."

According to The Philadelphia Inquirer, Schultz heard the commotion coming from downstairs while sitting in his room around 2 a.m. Sunday morning, then woke up his family and saw the brawl from a hallway overlooking the lobby.

He filmed the fight on his cell phone and uploaded it to YouTube, where it has garnered more than 532,000 views in less than 24 hours. Schultz can be heard on the video asking, "Did they just deck the bride?" and saying, "It's my freaking birthday, go to bed!"

Authorities have not identified the members of the two parties, but KYW reported that the deceased, a 57-year-old man, was the uncle of one of the brides. He suffered a heart attack at the scene and died Sunday night at a local hospital.

A spokesman for the Philadelphia Police Department, Lt. Ray Evers, said the incident began with a fight between members of one wedding party at the hotel bar. That fight escalated when they engaged with a second wedding party, who had come to the bar after an event at a separate venue.

"There was an issue with a lot of alcohol fueling the fights," Evers said.
