The Swedish royal regimes that were stolen have now been put out for international inquiry in Interpol's system, the Swedish Television SVT reported last Wednesday.
The funeral regimes -- a king's crown, a globus cruciger and a smaller queen's crown -- were stolen from a locked and alarmed security assembly in a cathedral outside Stockholm.
The police suspects the theft was planned but what the perpetrators are going to do with their catch, is a mystery to them.
"The stolen items are completely impossible to sell," police officer Maria Ellior from the Swedish Police National Operative Department told SVT.
According to SVT, there is a risk that thieves might try to destroy the objects in order to melt and sell the gold.
"That is something I would rather not even talk about, but everything is possible. The gold's value is nothing compared to the value of the objects themselves," research director Benny Beutelrock said to SVT.
The police are looking for witnesses and asking the public to keep their eyes open. The theft is classified as gross theft and the perpetrators risk up to six years in prison.
