The grandfather was playing with his grandchild in his parked car on the Ohmstraat after noon. According to the police, the child played with the steering wheel and pressed the horn a number of times. Suddenly they heard a hard blow and saw a woman with a big hammer on the hood of the car. Then she hammered the hammer against the side window of the car, near the man's head.
The grandfather got out while the woman walked away to her house again. A few neighbors came to the rescue and called the police. The woman has been interrogated on the desk and released in the course of the evening.
