German state police were questioning a 17-year-old asylum-seeker Tuesday after a tactical unit took him into custody on suspicion that he was planning a suicide attack in Berlin.
Police in Brandenburg state said the teenager was detained Tuesday in the village of Gerswalde, 60 miles northeast of Berlin, after they learned that he had sent a farewell message to family members on WhatsApp, telling them that “he had joined the jihad.”
The message was sent within the last week and Brandenburg authorities were told of it late Monday night by two other German states, Brandenburg police spokesman Torsten Herbst told The Associated Press.
He said that police were investigating and the teen was still being questioned, but thus far police had no evidence that a concrete attack was planned.
The federal Interior Ministry said it had no indications that an attack had been imminent.
The state Interior Ministry’s office identified the suspect as Syrian, but Herbst said investigators were checking to see whether he falsely registered as a Syrian but was actually from a North African country.
The teenager, whose name wasn’t released, came to Germany in 2015 as an unaccompanied minor and registered as an asylum-seeker. He has been living since 2016 in a home for minor refugees in Gerswalde, and was detained there in the Tuesday morning raid.
German security officials have repeatedly warned that the country is in the sights of international terrorist groups.
Germany saw a number of violent attacks by Islamic terrorists last year, including the truck attack on a Berlin market that left 12 victims dead and dozens injured. The attack, carried out by a young Tunisian man who had been denied asylum in Germany, was claimed by Islamic State.
