Carrying traditional weapons like bows and arrows, spears and tridents, the Liberation workers staged demonstration in the village to protest denial of justice to the families of those killed in a police firing last year, sources said.
They levelled the road with soil before throwing it open for public use, Sub-Divisional Police Officer (SDPO) Vikas Kumar said.
The agitation by the CPI(M-L) Liberation workers passed off peacefully, he said.
Four members of the minority community were killed in the police firing in Bhajanpur village on June 3 last year on a dispute over the passage to the local people near the site of an under-construction industrial unit.
