The man shot dead at Paris's Orly airport after attacking a soldier was under the influence of drugs and alcohol at the time, a judicial source said Sunday.
"Toxicology tests carried out on Sunday showed an alcohol level of 0.93 grams per litre in his blood, and the presence of cannabis and cocaine," the source said, a day after the incident at the French capital`s second-busiest airport.
The attacker, named as Ziyed Ben Belgacem, had shouted that he was there to "die for Allah".
Ben Belgacem, a Frenchman born to Tunisian parents, was known to police and intelligence agencies.
He had been investigated for links to radical Islam and was jailed for five years in 2001 for armed robbery, and again in 2009 for drug dealing.
