Nearly two dozen people have been injured after they clashed with policemen in a town in central part of the country.
The clash occurred in the town of Hetauda on Saturday, after the police tried to stop the agitating locals, who were obstructing the East-West Highway to press for their demands, including constructing an access road to their village.
They also demanded more effective measures to check pollution emitted by state-run Hetauda Cement Industry Limited in Hetauda, according to the officials.
The police had to resort to baton-charging and fired a few rounds of tear gas shells to disperse the crowd in an attempt to clear the highway.
Seven demonstrators were also arrested as they started hurling stones at the policemen.
However, the police succeeded in clearing the highway in 30 minutes.
The government has arranged special security on the highways in the wake of the forthcoming election.
As per the new law the administration can detain and fine people who were found involved in obstructing national highways.
The residents of villages near the cement factory have been padlocking the main gate of the factory demanding the control of emission from the factory and an access road through the factory to the village.
