One person was injured in the clashes and nearly 60 persons have been arrested, police said.
The Mahapanchayt was convened to protest the slapping of National Security Act (NSA) against BJP MLA Sangeet Som, they said.
"One person was injured and 50-60 people have been arrested," Meerut Divisional Commissioner Manjit Singh said.
The clashes broke out when rumours spread that some women were injured in caning by police at the venue, the village head said. Irate villagers started pelting stones on the police personnel deployed there, he said.
The local administration had refused permission for the Mahapanchayat, organised by Som's supported at Janata Inter College, and imposed prohibitory orders in the village.
The district administration had yesterday claimed after talks with leaders of the Mahapanchayat that they had agreed to postpone it.
