The students demanded the constitution of an external expert panel of psychological experts to counsel the students suffering from mental problems and an internal probe into the allegations made by Fathima's family.

Fathima's father had alleged that the professors named in the 19-year-old's suicide note had harassed her in the name of religion which led her to suicide.

According to the Chennai Commissioner of Police, AK Vishwanathan, a special team of the Crime Branch, Crime Investigation Department (CB-CID) was formed on Monday. Three professors have been interrogated in IIT-Madras guest house inside the campus so far.
