More details are emerging about the man all Europe’s police are now looking for.<br /><br /> It appears the main suspect in the Berlin truck attack was previously known to German police, and a 100,000 euro reward is being offered for his capture.<br /><br /> He has been identified as Tunisian-born 24-year-old Anis Amri, who had previously served four years in an Italian prison for burning down a school. The public has been warned he is armed and possibly dangerous. <br /><br /> “The North Rhine-Westphalian state office for criminal investigations has initiated proceedings with the federal prosecutor-general because of suspicions of the preparation of a criminal offence endangering national security. The general prosecutor in Berlin was leading the ensuing investigations,” said North Rhine Westphalia’s Interior Minister Ralf Jaeger.<br /><br /> It appeared Amri had entered Germany in July 2015 and had his asylum application refused. Since November he had been considered a threat, but could not be deported because some of his Tunisian documents were missing.<br />
