The trouble started when a large number of villagers gathered alongside the road as they wanted the chief minister to stop at Chausa and listen to their grievances on electricity and water supply in the area.
As the convoy did not not stop at the place, the locals pelted stones damaging a couple of government vehicles.
The chief minister's convoy, however, went ahead.
No harm was caused to anyone in the stone-throwing as policemen chased them away, the sources said.
