Seven people have been arrested after early morning police raids in Surrey, Sussex and London.
More than 200 officers from Surrey Police carried out the raids and seized £100,000 in cash, 70 fraudulently-obtained credit cards, 20 forged driving licences and 30 passports.
High-value cars including an Audi RS4 and a Porsche Cayenne were also seized.
The raids followed a 12-month inquiry by the force's economic crime department's money-laundering team.
Six men in their 30s and one woman in her 40s are being held in custody at Woking police station.
