Dawn timber-laundering raids cast doubt on 'sustainable' Brazilian wood

Police investigating suspected environmental scams swoop on state officials and businessmen in Amazon area known for woods used in furniture and decking

The raids began at dawn as the sun rose over the Tapajos river and more than 100 police swooped on a dozen locations in the most sophisticated operation yet against suspected timber laundering in Brazil - a practice that allows consumers in the US and Europe to buy flooring and furniture with what they think is a clear conscience.

More than 30 officials, local businessmen and sawmill owners were arrested in Pari state in the north of the country this morning as prosecutors targeted what they say is a criminal organisation that whitewashes environmental crimes and reveals the flimsiness of Brazil's logging controls.
