"This morning, the police neutralized the man threatening [people] with a cold weapon at Roissy-Charles de Gaulle airport," the Paris police prefecture said on Twitter.
The man died from the injuries, according to French media.
Reports earlier in day said French police opened fire at an aggressive man threatening people with a knife in the airport's 2F terminal servicing Schengen flights. The police repeatedly asked the man to drop the knife, but he reportedly ignored the demands.
According to French newspaper Le Parisien, the deceased was a 32-year-old homeless man who came to Paris from the French overseas department of Martinique. He was often seen at the airport and recently behaved aggressively. The incident occurred when the terminal staff called the police on the homeless man over the fact that he refused to move.
