A criminal investigation is prolonging an embarrassing spy scandal surrounding Credit Suisse and former top executive Iqbal Khan. 

Swiss banker Iqbal Khan as well as the private detective tasked to shadow him have asked for evidence linked to a confrontation in Zurich's banking district last month to be sealed, according to Swiss weekly «SonntagsBlick» (in German). This prevents the city's prosecutor from scanning mobile phones and other hardware from the security personnel in the criminal investigation of the event.

«All the involved parties have demanded that objects seized be sealed,» Thomas Fingerhuth, lawyer for the surveillance firm Investigo, told the outlet. The Zurich-based outfit was hired by Credit Suisse to shadow Khan after the wealth manager defected to UBS, a move it has since apologized for after sacking a top executive and a security overseer.

Benefits Spying

As a result, a court in Meilen, where Khan apparently filed the complaint, must weigh the privacy of the parties involved against the merits of the criminal probe. The matter is complicated by Investigo's past mandates shadowing benefits recipients, the paper reported.

This effectively makes Investigo's detectives assistants to civil service, meaning they are subject to secrecy requirements. «We can assume the matter will take some time to wrap up,» Fingerhuth said.
