The Trinamul-BJP face-off over vandalism at Visva-Bharati triggered yet another battle on campus between the Enforcement Directorate, a central agency, and the state police.

Amid murmurs that the saffron camp was determined to nail Trinamul on vandalism, the ED tiptoed into the campus on Wednesday to probe if money had been spent to mobilise the mob on Monday.

A day after the ED sought all complaints related to the contentious Pous Mela boundary wall from Bengal police, the latter on Thursday summoned the officiating chief security officer of Visva-Bharati, Ganesh Malik, to appear at Santiniketan police station in connection with a criminal case of forcibly taking away a cellphone from a freelance photographer earlier this month. VC Bidyut Chakrabarty had been named in the FIR of this case as well.

“We summoned the security officer as security personnel were involved in the case,” said Shyam Singh, Birbhum district police chief.

Sources said the state police took exception to the entry of the ED, which probes economic crimes, in the case of campus vandalism that Birbhum police had been investigating.

The police got a letter from the ED seeking copies of complaints and action-taken reports in all five complaints filed in connection with the wall issue. “We will write to the ED to know why,” said a senior police officer. Sources said the state police would start probing all pending criminal cases against the VC and other officials filed in the past year or so.
