Malini's relative Ramesh Hansdah, a former JMM General Secretary, demanded stringent action against "the person whose action abetted the suicide move by such a bright girl."
Malini's father had lodged a case against the person, reportedly her boy-friend.
Later, the body was cremated at Parvati Ghat here.
Allegedly upset over her boyfriend's notification on Facebook that she was dumped, Malini, a first year MBA student from Jharkhand, hanged herself in her hostel room last afternoon, Bangalore police earlier said.
Investigations revealed the person was in Bangalore recently and had a quarrel with Malini, a senior police officer said.
Malini joined the IIM-B last June, having worked at Infosys after completing her B Tech, according to the institute sources.
