'If the four students are found guilty by the probe committee, adequate action would be initiated against them. The university will not tolerate any form of ragging in the campus,' Bhuyan said.

Meanwhile, the All Assam Students' Union (AASU), Friday urged authorities of all educational institutions to adopt a zero tolerance policy while dealing with students involved in ragging.

'Let us make it very clear that there should be no compromise when it comes to taking action on students found involved in ragging. Authorities of educational institutions should deal with the menace of ragging with a firm hand,' AASU adviser Sammujjal Bhattacharya said.
