Austria has increased security measures over Christmas due to threats of Islamist terror attacks. The suspected targets should have been Vienna's Cathedral and a few other churches. The Tajik man arrested in Germany was allegedly part of a terrorist group discovered in Vienna. The police is suspecting an Islamist terrorist motive and a connection to the ISIS-K (Islamic State - Khorasan Province). Although the suspect fled, a few other suspected terrorists, namely a man from Chechnya, another Tajik man and a woman from Turkey, were arrested before Christmas. The fugitive was arrested in Germany and is awaiting extradition to Austria.
