The female student had lodged the complaint on October 3 to the NEHU authorities that a senior professor of the Rural Development and Agricultural Production department sent her lewd messages.
"We have been seeking suspension of the guilty professor. We have proof of his guilt and want to know what step has been taken on the complaint. However, no answer is forthcoming," said NEHU Students Union president Alexander D Sangma said.
The cell is asking for evidence to be given before any action is taken, Singhaih said.
The students, however, said evidence would be given when the woman's cell members come to Tura as the investigation cannot be held from Shillong.
