A bank worker was caught after his attempt to steal £1.2 million using customer details apprehended from his employer's computer system. According to press reports,Ansir Khan, an employee of Carter Allen Private Bank in Sheffield, wrote down stolen customer details in a complex code to avoid detection. He gave the details to accomplices who then rang up the bank pretending to be the customers, transferring money to their own accounts. When police raided Khan's home they found the conclusive evidences of his crime - his codes, which substituted letters in customer names for symbols and numbers, on pieces of paper. Detective constable Chris Stephens, a former district commissioner in the Scouts, used the Scoutmaster's A to Z handbook to crack the code, before pairing symbols with victim details. Khan, who has pleaded guilty to conspiracy to steal, will be sentenced along with 11 other gang members at Nottingham crown court. Between April 2005 and May 2006, the gang successfully stole £707,000 but another £500,000 did not go through. About one forth of the money stolen, £315,000, was retrieved and refunded to victims.
