German police hunting the killer who smashed a lorry into a packed Christmas market have revealed they are looking for a Tunisian man.
Investigators in Berlin revealed they had found ID papers in the truck under one of the seats.
The man, who has been identified only as Anis A by detectives, is thought to be 24 years old and from the city of Tataouine.
A source told Der Spiegel that the suspect also uses several other names.
