Students protesting at the campus before his arrival were hit by lathis or batons by the police; women students alleged they had been "manhandled". However, senior police officer Tushar Joshi said, "We had asked the students to demonstrate peacefully, but we had to use force because they wanted to block the way to the institute... we used minimum force."
The 55-year-old film school in Pune prides itself on quality cinema and has turned out some top filmmakers. It is governed by the Ministry of Information and Broadcasting.
Critics, including some students, say Mr Chauhan, an actor known for little apart from his role in the 1980s TV serial on the Mahabharata, lacks the stature to head an academic institution - an allegation denounced by the government. For nearly four months after he was selected as chair, students on campus went on strike to demand his removal.
"We have come to do our job," he said, before he presided over a meeting that focused partly on selecting the 14 members of the academic council for the film school. Among them are Rajkumar Hirani, the director of the blockbuster Munnabhai films and veteran actor Satish Shah.
