Frageand Naseem, from Livingston, who tricked staff into transferring millions of pounds into his personal accounts, has started giving lectures at the National Fraud Intelligence Bureau in London.
The dad of four was ordered to pay back £1,984,794 under proceeds of crime laws in May.
Naseem who channelled the cash into accounts in Dubai, Pakistan, Spain and Belarus has revealed intricate details of his scam to officers tasked with tackling major conmen.
He stole the cash from Royal Bank of Scotland, Barclays and HSBC, posing as bank staff to raid the accounts of wealthy clients before posing as an employee of a different bank to siphion the cash to his personal account in Dubai.
The 34-year-old was jailed for nine years in 2009 but had been in custody since 2006 and so was eligible for release last year. He faces a further eight years in jail if he fails to pay back the cash. NFIB bosses have denied paying Naseem for his lectures, claiming only his expenses were reimbursed.
