Bicycle Tyres punctured

In the last two or three weeks dozens of bicycle tyres were punctured in Willemspark, presumably with a knife or a skrewdriver. We assume that more bicycle owners may be victims, but only a few have reported. Their bicycles and carrier bikes were on Prinses Mariestraat, Frederikstraat and on the bridge Mauritskade/Frederikstraat.
It mainly happened during the weekends, in the late evening and in the course of the night. Police officers will do extra beats, both in uniform and in civilian clothes.
Residents are requested to call 112 when they see something suspicious.
