Three Polish supermarkets with the same name have been hit by explosions over the course of two days in the Netherlands.
On Wednesday, police said that an explosion damaged a store at 5.15am in the town of Beverwijk, 30km northwest of Amsterdam. Nobody was injured in the blast.
Dutch media have reported that the owner of the store also owns another Polish supermarket in Aalsmeer that was gutted by an explosion and fire in the early hours on Tuesday.
The same night, another blast hit a Polish supermarket in the southern town of Heeswijk-Dinther in the North Brabant province. Both shops were badly damaged but no injuries were reported, according to the authorities.
Police are investigating the blasts and have not revealed a possible motive.
All three stores were called Biedronka, but are not part of a large network of budget stores of the same name in Poland.
It was not immediately clear if the explosions were linked.
Police have appealed for witnesses. The blast in Aalsmeer, which happened around 3:00am on Tuesday, caused major damage to the store and nearby buildings, as well as setting a parked car on fire.
