Police in India are investigating the rape and murder of three young sisters in the western state of Maharashtra.

The bodies of the girls, aged six, nine and 11, were found in a well near the village of Murmadi in Bhandara district yesterday.

Post mortem results confirmed that each of them had been sexually assaulted.

Local people protested over the murders and demanded immediate police action.

It is understood the girls were last seen leaving for school on 14 February.

The incident comes just over two months after the gang rape of a 23-year-old woman on a bus in New Delhi that sent shock waves across the country.

India's criminal justice system is widely seen to have failed women who are sexually assaulted.

One woman is raped every 20 minutes in India, according to government statistics.

The conviction rate is among the lowest in the world and one of the key reasons is lack of proper investigation.
