Natarajan, arrested last night, was today produced before a magistrate. He is facing a case under section 354 A (sexual harassment) of the Indian Penal Code.
Senior Inspector R D Malekar of Kalwa police station who is probing the case said police registered the case against the professor after the college dean C Maitra filed a complaint, based on the report of an internal fact-finding committee.
The committee was set up when several female students complained of molestation or misbehaviour by Dr Natarajan.
