A bizarre incident on Sunday night onboard an Aer Lingus flight headed from Lisbon to Dublin has left one passenger dead. According to 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.”

Police also arrested a 44-year-old Portuguese woman who allegedly had four pounds amphetamine on the flight. It is believed that she was traveling with the Brazilian passenger.  

“The noise he was making was like something that I’d never heard before and wouldn’t like to hear again,” another male passenger told the Cork radio station 96FM, noting that the Brazilian passenger seemed to be having seizures. “It was like a deep anguish, that is the best way I can describe it. It was very, very troubled.”
