Hundreds of human rights activists and academicians on Wednesday sent a petition to President Pratibha Patil seeking a Central Bureau of Investigation (CBI) probe into the death of Aligarh Muslim University (AMU) professor S. R. Sirsa.

The petitioners, including democratic rights activists, teachers and gay rights activists, complained of “tardy” progress in the probe into the suicide case of Sirsa, former chairman of modern Indian languages at AMU, and blamed the police for the same.

They also demanded removal of AMU Vice-Chancellor P. K. Abdul Azis for his role in “persecution and harassment” of Sirsa, who was under suspension following a sting operation purportedly showing him indulging in unnatural sex, according to a copy of the petition sent to the President.

Meanwhile, Superintendent of Police Man Singh Chauhan has strongly denied “any pressure” in investigation into the sting operation.

The police has arrested two persons involved in the sting operation, the SP said adding so far no evidence against any AMU officials has been found.
