The police were reportedly investigating the leads related to the death of Anis Amri, a suspect in Berlin Christmas market attack.
On December 19, 2016, Amri, 24, rammed a stolen truck into a busy Christmas market in central Berlin, killing 12 people and injuring over 40. Amri then fled to Italy where he was shot dead by Milan police officers several days after the attack. It emerged later that he had pledged allegiance to Daesh, which is outlawed in Russia and Europe.
