On June 19, the individual had rammed a car carrying weapons and explosives into a police van as it drove in a convoy down Paris's Champs Elysees, and subsequently died.
"The arsenal of weapons discovered in the vehicle, highlights the scale of the terrorist act that was being prepared, which - if it had succeeded - would have had terrible consequences on human life," said Molins.
Molins said authorities had not yet identified the nature of orange smoke coming out of the car after the attack. In his car were an assault rifle, two pistols, ammunition and two large gas canisters, authorities had previously said.
Adam D was married to a Tunisian and had two children, added Molins.
