University of Hyderabad scholar Rohith Vemula's mother was admitted to the hospital on Sunday after she complained of chest pain.
She was admitted in the Intensive Care Unit of the Gachibowli Continetal hospital in Hyderabad.
"Radhika (Rohith's mother) was shifted from the protest camp on the campus tonight and taken to a private hospital after she complained of chest pain...heart pain and she is in the ICU," Rohith's brother Raja told PTI.
Various student groups have been protesting over the suicide of Rohith since last week.
Rohith Vemula, a Dalit PhD scholar, was found hanging at the CentralUniversity's hostel room on January 17.
He was among the five research scholars who were suspended by Hyderabad Central University in August last year and also one of the accused in the case of assault on an Akhil Bharatiya Vidyarthi Parishad student leader.
