French police have found stolen jewellery worth 18m euros ($25m; £15m) hidden in a drain in a Paris suburb.

法国警方在巴黎郊区一段下水道中发现被藏匿的价值180万欧元的失窃珠宝。

Police say 19 rings and three sets of earrings¹ were concealed²（隐藏） in a plastic container set into a cement mould（模具） at a house in Seine-Saint-Denis.

They were part of the spectacular robbery from Paris's luxury Harry³ Winston boutique（精品店） in 2008.

As many as four armed robbers stole at least 80m euros worth of jewellery from the shop.

The thieves - two of whom were disguised（掩饰，假装） as women - stormed the shop near the Champs-Elysee in December 2008 and stole nearly all its valuables.

They spoke⁴ French and another language, seemed well informed and knew the names of some of the staff, police said at the time.

Police have since detained（扣留） and questioned 25 people in connection with the robbery - one of the country's most serious for decades.

Harry Winston is situated⁵ on the fashionable Avenue Montaigne and attracts a wealthy clientele（客户） from around the world, from royalty⁶ to film stars.
