Burglars in Paris have made off with over €500,000 in fur coats, jewellery, handbags and other luxury goods after breaking into the home of Russian billionaire Nikolai Sarkisov, a police source said.
The 52-year-old is the co-founder along with his brother of RESO-Guarantee, one of Russia's biggest insurance companies.
His 600-square-metre (6,500 square-foot) duplex is situated on Avenue Foch, one of the most expensive streets in the French capital, near the Champs-Élysées.
The thieves struck in broad daylight last week while the businessman was away in the Mediterranean resort of Saint-Tropez.
It is understood the alarm was raised on Friday by a neighbour who found the door open.
Mr Sarkisov is yet to return to Paris and make a full inventory of the missing items, the source added.
The international jet set have been targeted in several robberies and muggings in Paris in recent years.
