Police in Italy are searching for a group of Russians who spent £75,000 on high quality Champagne at a top restaurant, before disappearing.

It has been reported that eight well-dressed Russians appeared at the exclusive Billionaire club in super rich Porto Cervo, the heart of Sardinia's Costa Smeralda.

Claiming to be the sons of wealthy oligarchs, the men proceeded to order bottle after bottle of Cristal Champagne, putting a total of 90 on the tab.

The men hardly seemed to be appreciating the fine wine, however, with a number of bottles said to have been sprayed around the club like Formula One drivers on the winners' podium.

It was agreed that the men would pay their bill the next day, but they have not shown up to do so.

"We trust our clients and there are some who choose not to settle their bills until the end of the summer," said Patrizia Spinelli, a spokeswoman for Billionaire's.
