US-based risk services company Stroz Friedberg has acquired the business of Tyrian Partners, a global financial investigations firm headquartered in London, in a move designed to expand its international forensic accounting service offering.

Tyrian Partners was set up in June 2013 by three former senior executives from risk mitigation specialists Kroll, Richard Abbey, Brian Stapleton, and Brendan Hawthorne, who have now been named as managing directors at Stroz Friedberg. Abbey, who was previously global head of financial investigations for Kroll, will lead the company's forensic accounting practice globally.

Tyrian Partners' 12 employees, who include accountants with Big Four experience, data analytic experts, and investigators with specialist financial training, will move into Stroz Friedberg's London office.

Michael Patsalos-Fox, CEO of Stroz Friedberg, said: 'We have long respected the founders of Tyrian Partners and the world-class forensic accounting work they provide on behalf of their clients in exposing fraud and recovering funds. As we join forces, I believe our collective talents will keep our firm ahead of the curve of modern investigation techniques and bring the best technologies to bear for our clients.'

Stroz Friedberg currently has offices in nine US cities, London and Hong Kong. Its forensic accounting team works with clients in resolving complicated business disputes and preventing, detecting, and responding to allegations of fraud.

Tyrian Partners' Richard Abbey said: 'Stroz Friedberg is a leading player in its industry. Combining the firm's multi-disciplined investigation talent, especially in the areas of digital forensics and cyber security, with Tyrian's depth of forensic accounting and financial expertise provides a clear advantage for our clients. It's a great opportunity to innovate financial investigations methods across a global platform.'
