Former Volkswagen CEO Martin Winterkorn has been charged in Germany over the car manufacturer’s diesel emissions scandal.
Prosecutors in Braunschweig say Mr Winterkorn failed to prevent the manipulation of engine software that let Volkswagen cars cheat on diesel emission tests.
They claim he knew about the deceptive software since at least May 25 2014, despite his public statements he only became aware of the issue shortly before the scandal broke in September 2015.
The prosecutors said Mr Winterkorn and four other defendants on fraud charges — all of them top Volkswagen managers — were part of an ongoing deception that started in 2006.
The company has admitted installing software that could tell when the cars were on test stands for emissions certification.
When the cars went on to everyday driving, the emission controls were turned off, improving mileage and performance but emitting far more than the US legal limit of nitrogen oxides, a class of pollutant that is harmful to health.
The prosecutors say that the defendants added a software update costing 23 million euro in 2014 in an attempt to cover up the true reason for the elevated pollution emissions during regular driving.
Mr Winterkorn and the others face from six months to 10 years imprisonment if convicted on charges of aggravated fraud involving serious losses.
Bonuses collected due to sales based on the deception could be forfeited. Prosecutors said bonus that could be forfeited ranged from around 300,000 euro to 11 million euro (£258,000 to £9.4 million).
Volkswagen has paid more than 27 billion euro in fines and settlements in the months and years since being caught.
The company apologised and pleaded guilty to criminal charges in the United States, where two executives were sentenced to prison and several others charged, although they could not be extradited.
