The professor has been placed under suspension. The orders in this regard have been issued on Thursday," Pro V-C G S Singhaih said.
Of the four students, one came forward and lodged a complaint with the authorities, he added.
The series of messages to the victim had caused her grievous mental agony leading to her submitting a complaint to the Pro V-C for action against the guilty professor. The matter was later escalated to the V-C of NEHU in Shillong who directed the Womens Cell for action.
The investigating team took statements of the victim and other complainants while also collecting relevant evidence into the case.
A report is expected soon.
