BERLIN (AP) — German authorities say they haven't uncovered any evidence linking a man who was shot and killed as he stormed a Paris police station to a terrorist network.

The Tunisian man, who went by multiple aliases and had applied for asylum in seven European countries, was killed Jan. 7 as he stormed the police station wielding a butcher's knife and wearing a fake explosives vest.

German police a week ago raided the suspect's apartment at an asylum-seeker facility in Recklinghausen on information from French authorities.

North Rhine-Westphalia criminal police head Uwe Jacob said Friday the man had a homemade Islamic State group flag on his wall and IS propaganda in his cell phone but it appeared he acted alone.

Jacob said authorities also found no evidence he was planning other attacks.
