German police have detained a 40-year-old Tunisian man who is a possible accomplice of Anis Amri, the man accused of carrying out the terror attack in Berlin last week. Amri was shot dead in Milan a few days after escaping the crime scene in Germany, where he rammed a truck into a Christmas market, killing 12 people and injuring dozens more. Police were led to the possible accomplice, whose name was not released, through Amri’s cellphone. “Further investigations will show whether the suspicions about him firm up,” said the public prosecutor general. In a video released by ISIS, Amri is seen pledging allegiance to the terror group before the attack.
