The driver who rammed his car into a pizzeria near Paris, killing a girl and injuring 13 people, had consumed large quantities of medication before setting off, a legal source told AFP on Tuesday.The incident on Monday night initially raised fears it was a new terror attack, coming just five days after a suspected extremist rammed a vehicle into a group of soldiers in Paris.
But investigators have ruled out a terror motive, saying the driver had allegedly tried to kill himself the day before, several sources have told AFP.
"He's confirmed that he had taken large amounts of medication," a legal source told AFP on Tuesday, asking not to be named because the information was sensitive. "
"We still don't understand his motive from what he's told us so far," the source added.
