Kolkata: Mocking left-leaning students for turning Jadavpur University into a "hub of anti-national activities", the RSS students' wing ABVP on Monday took out a protest rally outside the varsity.

ABVP and BJP activists took out the rally from Gol Park till the Jadavpur police station.

Hundreds of ABVP activists were seen crowding at the first of four police barricades. Some jostled with the police. Others climbed barricades and tried to jump across.

Addressing the ABVP workers, state secretary Subir Halder threatened to "chop off" the legs of Left students. "The Leftists have turned the university into a den of anti-national activities. We will not allow this... If these Leftists dare to venture out of the university, we will chop off their legs," he said.

The rally triggered clashes and caused tension in the campus. The screening of Vivek Agnihotri’s film Buddha In A Traffic Jam also triggered problems between the two warring sides.

Police declared the assembly to be unlawful and repeatedly urged the protestors to go back and not to break the barricades.

A section of students and faculty members also staged demonstration inside the campus against the ABVP’s bid to “saffronise” the varsity.

Students of the Jadavpur University crowded at their gate during the police-ABVP stand-off. "They wanted to come here and attack us. They were stopped by the police today. They will try again and we will be at this gate, ready and waiting," said Sounak Mukhopadhyay, a JU student leader.
