Danish police are investigating the theft of what is said to be the world’s most expensive bottle of vodka.

The bottle of Russo-Baltique which was stolen from Cafe 33 bar in Copenhagen is priced at £960,000.

Police investigator Knud Hvass said it is too early to say whether the perpetrator had broken in or used a key.

Nothing else was stolen.

Denmark’s TV2 said the bottle was made with 6.6lbs of gold and the equivalent amount of silver, with a diamond-encrusted cap.

Bar owner Brian Ingberg, whose bar has 1,200 vodka bottles, told Denmark’s Ekstra Bladet tabloid that the bottle resembles a vintage car front.

Mr Ingberg said the bottle was uninsured and on loan from a Russian businessman.
