Agitated by the killing of a 32-year-old man and a teenager by unknown assailants and then hanging them from a tree in the village under Balumath police station limits, villagers blocked the road near the police station with the bodies, the police said.
When the police went to take the bodies for post mortem, the protestors hurled stones at them, injuring civil SDO Kameshwar Narayan, Assistant Sub-Inspector of Balumath police station Shyamdev Mishra and four other policemen, Superintendent of Police Anup Birtheray told reporters.
The stones were hurled even after a peace meeting following the incident, according to the police.
The police, quoting the villagers, said the two persons had left their homes with animals for Tutilawa village in the neighbouring Chatra district for the annual animal fair when the incident happened.
