The joint action committee for social justice of the Hyderabad Central University (HCU), the students organisation which is leading the protest over Rohith Vemula issue, on Sunday called for boycott of classes "at all the (college) campuses" in the country tomorrow.

It has also issued a national call for a public protest gathering at Ambedkar statues all over the country.

The call is in protest against alleged police brutality on students of HCU and in Kozhikode, Mumbai and Chennai, the JAC said in a release.

It also demanded dropping of all charges against students, faculty members at HCU and elsewhere in the country and immediate removal and arrest of P Appa Rao, Vice Chancellor of HCU, under the SC/St (Prevention of Atrocities) Act.

Its other demands include "demilitarisation of the campus, action against police for the unnecessary and targeted violence, false detention, misinformation about the detained people and physical and sexual assault on women students and faculty, and introduction of Rohith Act," according to JAC's press release.

Several students were arrested following the attack on VC's residence on March 22 after Appa Rao, who had gone on a long leave after Dalit scholar Vemula's suicide, resumed duty.
