Police are investigating after windows at a primary school in Siegburg were smashed and a moving car’s windshield was damaged. Officers are looking into two incidents. In the night from Monday, 9 November to Tuesday, 10 November, unknown offenders damaged window panes at a school building on Chemie-Faser-Allee. A witness had seen the windows intact on Monday evening around 6.30 pm, but on Tuesday children noticed multiple holes around 11.15 am. Police found several holes in the glass and a metal ball at the scene, but they are still unsure whether it was shot or thrown. A second incident happened on Thursday, 12 November at about 8.25 pm on Frankfurter Straße. A 56-year-old man driving on the route between the roundabout Wilhelm-Ostwald-Straße/Frankfurter Straße and a disused level crossing heard a loud bang and later discovered fresh damage to the windshield. He believed no other vehicle was nearby and reported the damage to police. The criminal investigation is treating both events as suspected property damage. Investigators are also checking whether the incidents are linked and whether they could be traced back to the same suspects. Witnesses who saw anything suspicious during the relevant times are asked to contact the police at 02241 541-3121.
