Visva-Bharati Vice Chancellor Bidyut Chakraborty, who had earlier courted several controversies, triggered a fresh row on Wednesday over a purported audio clip of him threatening to close down the premier central university. In the viral audio clip, which could not be verified, Chakraborty was heard telling the faculty and non-teaching staff: “I will ensure Visva-Bharati is closed down. But I am not issuing any threat.” “Visva-Bharati has become a hotbed of thieves and dacoits. Otherwise how come (TMC leader) Anubrata Mondal gets away by saying the VC is insane,” he said.
