You have the right to access the public road without fear and obstruction. The village committee lacks the authority to obstruct the public road. The act of blocking the public road and issuing threats against those seeking access to it constitutes an offence.
It is imperative that you promptly file a complaint against the individual who has illegally obstructed the road.
Whoever voluntarily obstructs any person so as to prevent that person from proceeding in any direction in which that person has a right to proceed is said to wrongfully restrain that person. It is punishable under Section 341 of the Indian Penal Code (IPC).
You should also move an application to the local Sub-Divisional Magistrate for taking action against the miscreants under Section 145 of the Code of Criminal Procedure (crpc).
