The two faculty members sat on the fast outside the university.
The SC/ST Teachers' Forum, meanwhile alleged that the university's action against the two faculty members was taken "in a fit of vindictiveness" and sought revocation of their suspension.
The faculty members-- K Y Ratnam, Head, Centre for Ambedkar Studies and faculty member of Department of Political Science and Tathagata Sengupta, faculty member of Department of Mathematics-- were yesterday served with suspension notice for allegedly not informing the University about their detention by police on March 22.
"Ratnam and Sengupta have commenced an indefinite relay hunger strike in protest against their unjust and casteist suspension," the Forum said in a release.
Ratnam and Sengupta were detained when police dragged away protesters who besieged the official residence of vice-chancellor Appa Rao on March 22, protesting against the latter resuming his office after a long leave.
"In a fit of vindictiveness, UoH issued suspension notices yesterday, several months after they were already targeted for arrest simply for the noble act of requesting the police to desist from beating and brutalising the students during the lathi charge on March 22," it said.
The University of Hyderabad, popularly known as HCU, has witnessed sporadic protests over the suicide of Dalit research scholar Rohit Vemula, with protesting students demanding removal of Appa Rao from the VC's post.
Appa Rao has been booked under the SC/ST (Prevention of Atrocities) Act and for abetment of Vemula's suicide. The university has been on the boil since Vemula committed suicide on the campus on January 17, subsequent to which VC Podile went on a leave amid protest by students.
"We demand justice for Rohit Vemula and his family, and an end to caste atrocities and discrimination on university campuses," the Forum added.
Senior Dalit Prof Ratnam has been targeted in a casteist manner by Appa Rao repeatedly since 2002, starting from when Appa Rao shifted him from his position as a warden to specifically tend to sanitation in hostels, the release alleged.
"Appa Rao's presence as Vice-Chancellor of the University and his continued actions of socially boycotting Dalit students, being responsible for Rohit's death, then again creating a social boycott and cutting off access to food and water on campus," It alleged.
