Results of a post-mortem examination on the Berlin Christmas market attacker Anis Amri indicate he was a frequent drug user, an Italian official has said.
Amri, who ploughed the lorry into a busy Christmas market on 19 December and was subsequently shot by police, was a frequent user of both cocaine and hashish.
The official said it was not possible, however, to determine whether Amri had used the drugs before the massacre that killed 12 people and injured dozens more.
Amri had fled the scene following the attack, but was later identified after his wallet, identification, phone and fingerprints were found at the crime scene.
The 24-year-old failed Tunisian asylum seeker was killed four days later during a routine stop by police in a Milan suburb.
Investigations confirmed a video of Amri pledging allegiance to Isis that was released by the group following his death to be authentic.
