At around 1 p.m., a man entered the church in Alt-Karow Street and started to damage the interior. He then withdrew to the organ balcony and according to police reports kept  shouting  incomprehensibly.  The attacker fought off the approaching officials with a wooden stick while continuing to wreak havoc with church furnishings. The man refused to calm down, and after additional support arrived,  struck out at an officer  who approached him with a protective shield.

The assailant was finally arrested and received medical treatment in a hospital. His motives remain unknown. Fortunately, none of the church staff suffered injuries during the incident.
