Philadelphia police were called to a hotel early Sunday to break up a brawl between guests of two wedding parties, and when it was over one man was dead of a heart attack and three people were cited for crimes.

A guest at the Sheraton Society Hill Hotel shot cellphone video of the brawl. The video shows a chaotic scene in which uniformed police officers try to separate and subdue several guests. One officer is seen repeatedly striking at least one person with a baton. A woman's blood-curdling screams are also heard.
