A bizarre incident on Sunday night onboard an http://www.theguardian.com/business/aer-lingus" rel="nofollow - Aer Lingus flight headed from Lisbon to Dublin has left one passenger dead. According to  http://www.irishmirror.ie/news/irish-news/horror-man-dies-aer-lingus-6657970" rel="nofollow - the Irish Mirror , a 24-year-old man “ran amok” and had to be restrained after he became violent and started “biting another passenger.” 

The crew reported that the man — who  is reportedly from Brazil and studying in Ireland — fell unconscious after he was restrained. The Irish police said in a statement that “the flight was diverted to Cork airport when the man on board became agitated. He was attended to by a doctor and nurse who were on the flight but was pronounced dead at the airport at 6:40 p.m.”
