Seven time Formula One world champion Michael Schumacher remains in a coma after sustaining head injuries during a skiing accident in the French Alps resort of Meribel, with the cause of the mishap now suspected to be a "technical error".

According to local police authorities, a glitch could have been the reason for Schumacher to fall. But it is not known what the technical error could have been. Initial reports suggest there was no collision with other skiers.

The accident took place at about 11:00am local time in the upmarket Meribel resort located at the popular Three Valleys area. Schumacher, 44, was brought to the hospital after striking his head on a rock while skiing. He was wearing a helmet during the accident and was said to be conscious after the fall. He was airlifted by helicopter to a hospital shortly after the mishap.

German media reports have said Schumacher's condition worsened and is "life-threatening" following his hospitalisation. Some reports, citing neurology experts, point out he might have suffered a brain haemorrhage, given the nature of the ongoing treatment.

Schumacher retired from motor racing for a second time in 2012 ending a 19-year career, after being the most successful Formula One driver with 91 race victories and seven world championships.
