The so-called ‘Suisse Secrets’ leak of bank client information hit the headlines in 2022, suggesting that criminals and corrupt officials held accounts at Credit Suisse.
This followed a series of press exposés based on data stolen from international law firms connected with the financial sector.
The OAG is investigating suspected breaches of economic intelligence, trade secrets and banking secrecy laws.
The OAG would not say who initiated the complaint or against whom the investigation is specifically directed. Last year, a Swiss newspaper said it has rejected the offer of leaked data as it feared criminal prosecution.
Switzerland tightened its banking secrecy laws in 2015 in the face of a spate of data thefts from Swiss banks.
The law is intended to punish anyone who profits from leaking data but also targets journalists who receive such information.
