Spanish police have arrested more than 80 people who laundered money obtained by cheating at least 4,500 people out of money, mostly via so-called Nigerian or '419' scams, Spanish Authorities report.
Members of the group, 80 percent of whom were Nigerian, allegedly took receipt of money scammed from victims in the US, Canada and Germany and laundered it by transferring the money on to Nigeria, police added.
The majority of the cash handled was obtained using the classic Nigerian, or '419' scam. This involves fraudsters promising their targets a large amount of cash in exchange for a small upfront payment.
If this payment is forthcoming, scammers either escalate their demands, or disappear, leaving their victims out of pocket.
Up to 200 internet cafés were investigated in the investigation by Spanish police.
Raids also uncovered fake passports used by gang members which had been created using photographs of famous celebrities.
