Security forces in eastern Tunisia on Tuesday arrested a man suspected of close links to Anis Amri, the Islamic State supporter who allegedly drove a truck into a Christmas market in Berlin, killing 12 people, local reports said.
The unnamed man was held in the coastal city of a Sfax and was expelled from Germany last year, the local media reports said citing investigators.
The suspect is said to belong to a terrorism cell active in Germany which has German, Russian and Turkish members.
A rookie police officer shot dead Amri, a 24-year-old Tunisian, when he allegedly opened fire on police during a routine security check in a Milan suburb on 23 December.
Amri was accused of ramming a heavily laden truck into crowds at Berlin's popular Breitscheidplatz market on 19 December. Besides the 12 people who died, 56 were injured in the attack.
