Police say a man has been charged in connection with a big brawl that broke out among people attending two different wedding receptions in a downtown Philadelphia hotel.

The fight involving dozens of people happened early Sunday in the Society Hill neighborhood. Police say a 57-year-old suffered a fatal heart attack outside the reception, but they don't know if he was involved in the fights.

Philadelphia police said Monday that one person has been charged and more arrests are expected. Authorities say 26-year-old Westfield, N.J., resident Matthew Sofka is charged with aggravated assault and other counts. A message left at a telephone listing for him was not immediately returned.

Police say the investigation is continuing and they expect more arrests. They don't know what started the brawl but say alcohol was involved.

The spreading altercation was caught on video by Max Schultz, a 15-year-old from Camp Hill in central Pennsylvania, who was in Philadelphia with his parents to see the historic sites and celebrate his birthday. Schultz said he was sleeping when noise from the fight awoke him and he went to check it out around 2 a.m.

He went to an atrium where he looked down on the fight, took out his cell phone and began recording it -- after he had to frantically start deleting files so he had enough memory for the video of people sparring while wearing tuxedos and ball gowns.

"I just saw a lot of people going at it," said Schultz, who later posted the video on YouTube. "It was obviously pretty chaotic."

Dozens of police arrived and began to get control of the situation, he said. "The situation could have been much worse if (the police) hadn't been there," he said. "I think they did what they had to do to keep people under control."
