Interpol hunts Liechtenstein mole

A former data entry clerk at LGT Group is being sought by Interpol for alleged theft, computer security crimes and counterfeiting and forgery.

Heinrich Kieber has been identified as the informant who allegedly stole client information from the bank and sold it to authorities in the UK, the US and Germany, the Telegraph reported.

Data contained on computer discs he sold is believed to uncover tax evasion by approximately 1,400 clients of LGT, thought to run into billions of dollars.

German secret investigators allegedly paid Kieber between €4m and €5m ($6m and $7.5m) for data on holders of accounts with the LGT banking group. He's also believed to have sold similar client information to US investigators.

The Kieber case follows a recent report into tax evasion investigations which was compiled by US Senator Carl Levin. The report suggests the US is losing $100bn a year through evasion.
