Swiss prosecutors open Berlin truck attack investigation
Swiss prosecutors have opened criminal proceedings against unnamed people in relation to the Berlin truck attack.
On 19th December Tunisian Anis Amri drove the vehicle into a Christmas market in the German capital, killing 12. Amri was shot dead by Italian police in Milan a few days later.
Investigators are trying to determine if Amri had help in the planning of the attack from people based in Switzerland.
Swiss authorities are examining reports Amri spent two weeks in Switzerland in 2015 and was on his way to Zurich on a bus last year when he was arrested by German police in Freiburg on immigration charges. He was later released as Tunisia refused to issue the papers needed to deport him.
