The Versace and Prada clothes seemed a little lavish for a teenager. Then there was the Louis Vuitton luggage, the limousines, the penthouses overlooking Sydney Harbour. How on earth could a 14-year-old schoolboy afford this celebrity lifestyle, his mother wondered.
She found out that her son was masterminding an eBay scam that had netted him A$200,000 - and that Australia's big four banks were helping him launder the money by allegedly showering him with bank accounts and debit cards.
Neither the boy nor his mother can be identified for legal reasons, but details of the bizarre case have emerged from documents lodged with the New South Wales Supreme Court. He was arrested at school after his frauds were linked to an IP address attached to a classroom computer.
The woman, who lives south of Sydney, is seeking damages from the four banks - the Commonwealth, ANZ, Westpac and National Australia Bank - and an apology for "unconscionable conduct".
The boy sold non-existent items on eBay, the online auction site, at one stage earning more than $6000 a day. His mother's suspicions were aroused when he began booking penthouses costing $4300 a night and hiring limousines to go to the beach.
