There are so many grenades on the streets in Amsterdam because the price of hand grenades is now very low: between 5 and 20 euros each, according to police. This year there are already fourteen deposited. Research shows that the grenades are always put down in a targeted way to threaten the catering sector and stores. The mayor of Amsterdam has closed a restaurant and a clothing store on the Bijlmer square, where two grenades were found in a short time.
