Police fired teargas shells on villagers demanding jobs at Tata Motors small car project in Singur shortly after the arrival of company managing director Ravi Kant on Friday.
"After arriving in Singur, Kant went straight inside the project site to discuss the progress of work with senior officials," company sources said.
About 100 villagers, who land was acquired because of the project, gathered near the boundary wall at Khaserbheri-Monsatala and began demonstrations. They pelted stones when the police intervened.
The police, who were deployed inside, fired teargas shells to break up the demonstration, according to eyewitness account.
