The Japanese camera and medical equipment maker Olympus and its UK subsidiary Gyrus Group will be prosecuted by the British Serious Fraud Office. They have been charged with providing misleading, false or deceptive material in accounts for Gyrus Group. Olympus's acquisition of Gyrus was one of the deals called into question as a 1.7 billion dollar accounting fraud came to light in 2011. Three former executives have been given suspended jail terms over the scandal. It is one of the biggest financial frauds in Japan's history.
