The case was lodged after 14 girls, all first year students of the institute, lodged an FIR against its director in this regard at Bawngkawn police station here last evening.
The alleged molestation took place in September when they sought admission in the institute, police said adding the students were angry at this but thought that it was the process of medical test.
Later, advised by their seniors, the girls talked to their parents about it and then decided to lodge an FIR.
Vanramchhuangi, a woman rights activist who accompanied the girls in the police station, said that more students might come forward as many of them were out of Aizawl now.
