Tunisian is detained by Berlin attack investigators
A Tunisian man has been arrested on suspicion of being involved in last week's truck attack on a Christmas market in Berlin.
German federal prosecutors said the 40-year-old was detained during a search of his home and business.
Officials said the man's number was saved in the mobile phone of Anis Amri, a fellow Tunisian believed to have driven a truck into the market on December 19. They said further investigations indicate that the man "may have been involved in the attack" in which 12 people died.
Prosecutors have until this evening to determine whether the case against the man holds up to the extent they can seek a formal arrest warrant, which would allow them to keep him in custody pending possible charges.
Investigators are trying to determine whether Amri had a support network in planning and carrying out the attack, and in fleeing Berlin. They are also trying to piece together the route he took from Berlin to Milan, where he was killed in a shoot-out with Italian police.
