"Is this protest due to the banning of drugs, liquor and charas?" he said in a Facebook post.
The comment comes in the backdrop of JU students protesting on the streets of Kolkata demanding the resignation of the VC, the Pro VC and the registrar of the varisty in the wake of alleged police assault of students in the early hours of September 17.
Thousands of students had marched through the city's streets on Saturday demanding resignation of JU Vice-chancellor Abhijit Chakrabarti and West Bengal Governor K N Tripathi intervened to end the four-day old stalemate in the prestigious educational institution.
Students from Presidency University, Calcutta University and other educational institutions joined the march in a show of solidarity.
JU students have boycotted classes to press the demand for the VC's resignation. Those in the mass communication department boycotted their examination on September 18.
