A millionaire has been charged with murder after allegedly killing his security guard as he came home from work.

Mohammed Nisham is accused of driving his car into the guard because he was too slow opening the house gates.

The victim, K. Chandrabose (50), was pinned against a wall - and police believe he was then hit with an iron rod.

After spending two weeks in hospital on life support, the he died on Monday in the southern Indian state of Kerala.

Mr Nisham is already facing a separate court case after allowing his son (9) to drive a Ferrari on a public road in 2013.

According to past police reports, he owns 18 luxury cars worth US$4m (€3.5m) - including a Lamborghini and a Bentley.
