Bolivian authorities say they've seized 17 properties from a provincial clan ostensibly in the gravel business that it suspects of laundering drug money through real estate.
Cochabamba police chief Vladimir Pol says police were unable to capture any of the seven wanted brothers of the Cossio Rojas family when they raided the properties Wednesday. He says they did arrest two of the men's wives.
Prosecutors say some of the properties are in neighboring Chapare province, Bolivia's main coca-growing region.
Authorities say cocaine traffickers and their labs are getting more sophisticated in Bolivia, with Colombians and other foreigners increasingly involved in its illegal drugs trade.
