“They have stolen a safe from a building which is situated outside of the high-security zone,“ said Royal Court press spokesperson Bertil Ternert to daily Aftonbladet.

According to the police website the burglars struck against a building adjacent to a coffee shop on the Solliden estate in the early hours of Thursday.

“It is located just outside of the high-security zone and the café is run at the request of the King,” Ternert told the paper.

Police said that the thieves had got away with several items of value and escaped in a stolen car they found nearby.

Both the King and Queen were in residence at Solliden at the time of the burglary on the estate.

“They have been informed of what has happened and have been following the investigation over the course of the day,” Ternert told Aftonbladet.

The stolen vehicle was later found on the Borgholm castle ruin parking.

The Solliden Palace has been the summer residence of the Swedish Royal Family since its completion in 1906 and is situated near the Borgholm castle ruin on the island of Öland, in the Baltic Sea, off the south eastern coast of Sweden.
