Patna, Aug 27 - A Dalit headmaster was allegedly abused, humiliated and beaten after he refused to pay a bribe demanded by an upper caste man in a Bihar village, police said Thursday.

Madheswar Ram, headmaster of a government primary school in Mehi village in Aurangabad district, was attacked early this week when he refused to pay Rs.50,000 to Ayodhya Yadav, a villager.

'I was abused and beaten for not paying extortion,' Madheswar Ram said. He named Yadav as the main accused in the case.

Ram told police that the school was given Rs.230,000 for construction of a building. But Yadav demanded the bribe which he refused to pay.
