Jamia Millia Islamia university authorities, rubbished the allegations of threat as baseless and maintained that it was "improper" on his part of having petitioned the President without approaching the varsity administration.
Police officials said that they have received the complaint but no FIR has been registered in this connection.
"Certain members of the staff association and other representative bodies entered my department today shouting hostile and intimidating slogans and threatening me with dire consequences. This was an unjustified reaction to complaints sent by me to the President," Obaid Siddiqui, professor at Jamia's Mass Communication Centre, alleged in his complaint.
A senior police official said, "we have received the complaint and the matter is being looked into. No FIR has been registered in this regard and his request for police protection will be examined".
Siddiqui, had sent a petition to the President who is Visitor to the university, objecting to introduction of 5 per cent seats for wards of Jamia Millia Islamia employees, despite Delhi High Court having quashed a similar arrangement in 1997.
