A 2,500-year-old golden helmet considered one of Romania's greatest treasures has been recovered more than a year after it was stolen during a raid on a Dutch museum. It and two golden bracelets dating back to about 450BC were unveiled as having been returned to the museum on Thursday, secured behind a glass case with two armed police guarding them. A third bracelet has not yet been found.

The theft of the Coțofenești helmet and bracelets by an armed gang who broke into the Drents Museum in Assen caused outrage in Romania and raised questions about security for priceless artefacts on loan to other countries. It's a long-awaited result, Romanian prosecutor Daniela Buruiană told journalists, adding, We are happy that we are now witnessing here the recovery of the Romanian artefacts.

The treasures, which date from the Dacian era - an Iron Age civilisation that existed roughly where Romania is now - had been on loan from Romania's national history museum when they had been stolen. Their theft prompted a spat between the two governments that led to the Dutch government paying a reported €5.7m (£5m; $6.5m) in insurance compensation. Romanian officials refused to discuss what would happen to that money now.

Robert van Langh, director of the Drents Museum in the northern Netherlands, reported that the helmet had been slightly damaged but could be restored, while the bracelets remained in perfect condition. Romanian prosecutor Rareș-Petru Stan praised the collaboration between authorities, insisting the investigation remains ongoing to locate the remaining bracelet.

This incident highlights the ongoing challenges faced by museums in securing invaluable national treasures while addressing international cultural heritage policies. The former head of the national history museum in Bucharest was notably criticized for allowing such sensitive treasures to be loaned abroad amid inadequate security provisions.
