Police Looking for 'Amateurish' Thieves Accused of Bombing Dutch Gallery in Heists of Warhol Prints

A series of brazen heists involving exploding bricks and stolen Andy Warhol prints have stumped Dutch police who are now hunting for an elusive gang of "amateurish" criminals.

The latest in a string of bizarre incidents occurred on Tuesday night in the northern Dutch city of Groningen when thieves used a brick of explosives to blast their way into the Groninger Museum, setting off an alarm that alerted the police.

When officers arrived at the scene, they found that two Andy Warhol prints had been stolen, along with a third print by the Dutch artist Jan Dibbets.

Police are still searching for the thieves, but they say they have some leads.

They believe that the gang is based in the Netherlands and that they have been targeting museums and galleries in the country for several months.

The police have described the thieves as "amateurish" because of the way they have carried out the heists.

In each case, they have used a brick of explosives to blast their way into the building, setting off an alarm and alerting the police.

The thieves have also been careless in their handling of the stolen prints.

In one case, they left a fingerprint on one of the prints, which the police are now using to try to identify them.

The police are urging anyone with information about the gang to come forward.

They are also warning museums and galleries to be on the lookout for the thieves and to take steps to protect their collections.
