(BLOOMBERG) - Credit Suisse Group said it reached a settlement with its former wealth-management executive Iqbal Khan and a private detective firm, calling to a close a spying scandal that rocked one of Europe's biggest lenders and ultimately led to the ouster of its chief executive (CEO) Tidjane Thiam last year.

"All involved parties have agreed to settle, and this matter is now closed," a spokesman for the bank said on Sunday (July 25), confirming that it had reached a settlement with Mr Khan, his wife and the private detective firm Investigo. No further details were disclosed.

A probe by Swiss financial regulator, Finma, over the company's surveillance activities is ongoing.

In 2019, Credit Suisse hired a private investigator to spy on Mr Khan, once seen as a potential successor to the CEO before defecting to rival UBS Group.

The incident culminated in a physical confrontation in downtown Zurich between Mr Khan and the men who followed him, shaking Switzerland's financial world and setting off investigations by Zurich's prosecutor and the company's board of directors.

The settlement would close a chapter for Credit Suisse as it seeks to move past a string of recent scandals. It faces an exodus of senior bankers after the collapse of Archegos Capital Management and Greensill Capital. In the aftermath, new chairman Antonio Horta-Osorio pledged a review of the bank's businesses.

Credit Suisse is set to report its second-quarter earnings on Thursday.

The settlement was first reported by Swiss newspaper NZZ am Sonntag.
