The investigation into Michael Schumacher's catastrophic accident has focused on whether his ski helmet was weakened by the camera attached to it.
The helmet shattered when the Formula One ace hit a rock while skiing at the French resort of Meribel, leaving him brain- damaged and fighting for his life. Police are trying to establish why it smashed so dramatically - as Schumacher was only skiing at a moderate speed.
A source close to the investigation said: 'Technically the equipment seems to have all been in good order. But why did the helmet explode on impact?
'The laboratory has been testing to see if the camera weakened the structure.'
