Dutch Art Heist Trial: Suspects Bernhard Z. and Jan B. Face Charges Over Million-Euro Theft

Dutch prosecutors have recommended prison sentences of up to 66 months for three men accused of orchestrating a high-profile heist at the Drents Museum in Assen. The trial, which began on April 14, 2026, concerns the theft of several priceless Romanian artifacts, including the 2,500-year-old gold Helmet of Coțofenești.

The Public Prosecution Service (OM) sought the highest penalty of 66 months in prison for 35-year-old Bernhard Z., who refused to enter into a plea agreement with authorities. In contrast, prosecutors recommended sentences of 44 months for the other two suspects, 21-year-old Jan B. And 37-year-old Douglas Chesley W. These lower recommendations follow agreements reached between the OM and the two men.

The Museum Heist

The robbery took place during the evening of January 24 and into the early hours of January 25, 2025. Thieves gained entry to the Drents Museum by using explosives to force open a door and subsequently used sledgehammers to smash through display cases.

The suspects stole four highly valuable Romanian artworks: the Helmet of Coțofenești, which dates back to the fifth century BC, and three gold bracelets. The artifacts were on loan to the Dutch museum from a gallery in Bucharest.

Police arrested Douglas Chesley W. And Bernhard Z. Shortly after the incident. Jan B. Was taken into custody at the end of April 2025 following a covert police operation. Despite the arrests, the stolen items remained missing for over a year.

Recovery and Missing Artifacts

The recovery of the treasures occurred in April 2026 after the prosecution struck a deal with Jan B. And Douglas Chesley W. As part of the agreement, the two suspects returned the gold helmet and two of the three gold bracelets.

Authorities revealed the recovered items during a news conference at the museum, noting that the helmet was in near pristine condition, with only a minor dent. One gold bracelet remains missing.

The prosecution stated that there is no indication that Jan B. Or Douglas Chesley W. Are in possession of the final bracelet. Regarding the ongoing search for the missing piece, the prosecutor’s office stated:

This does not mean, however, that the search for it has ended. It continues.

Trial Evidence and Charges

The suspects face multiple charges, including theft and the destruction of the museum. Prosecutors also accused the group of using a firework bomb to damage the facility. Jan B. And Bernhard Z. Are accused of stealing and subsequently burning the getaway vehicle used during the crime.

To link the suspects to the heist, the prosecution presented evidence including CCTV footage and DNA traces. These traces were discovered on glass fragments and shards of gold recovered from the scene.

During the proceedings, all three suspects declined to confirm or deny whether they recognized themselves in the surveillance footage provided by the prosecution.

Institutional and Financial Fallout

The theft caused significant repercussions in Romania and within the Dutch government. The head of the Bucharest museum that had loaned the artifacts to the Drents Museum was dismissed from their position for allowing the works to be lent out.

In anticipation of a potential payout following the loss of the priceless relics, the Dutch government had set aside 5.7 million euros (approximately $6.5 million). The recovered items are expected to be returned to Romania.
