A wrongful death lawsuit has been filed against Red Bull.
The suit claims a man in Brooklyn suffered a fatal heart attack as a result of consuming the energy drink.
His family says he was a regular drinker of Red Bull, and that he died shortly after having one in 2011.
The attorney who filed the $85 million lawsuit says Red Bull contains stimulants that are more dangerous than the company lets on.
Red Bull would not comment on the lawsuit, but said the drink is safe.
