Belgium charged nine people with human trafficking and money laundering on Wednesday for their alleged roles in a gang suspected of bringing women from China to be sex workers in Europe.
Some 300 Belgian police detained 27 people in raids across the country on Tuesday and seized bank notes worth about 1.5 million euros ($1.6 million) along with 4 tonnes of coins, federal prosecutors said.
Another person was detained in Spain and a further two in Switzerland after similar raids. Belgian investigators want them to be extradited.
