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 pollutions emitted by state-run Hetauda Cement Industry Limited in Hetauda, according to the officials. 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.
