A teenage girl in the eastern Indian state of Jharkhand has been raped in apparent revenge for an alleged assault on another woman, police say.

Three people were arrested, including a village head who is accused of approving the alleged crime.

The 14-year-old girl was allegedly raped this week after her brother was accused of assaulting a woman.

Violence against women remains deeply entrenched while calls to address the problem have grown in recent years.

Scrutiny of sexual violence in India has grown since the 2012 gang rape and murder of a student on a Delhi bus.

The government tightened laws on sexual violence last year after widespread protests following that attack.
