The four students are Sifatul Islam of the Philosophy department, Saiful Islam Rasel of Soil, Water and Environment department, Mostafizur Rahman Rafiz of Information Technology Institute and Abdur Rahman of History department.
Sifatul began the hunger strike in front of the ‘Raju Sculpture’ around 3:30am on Monday in protest against the rape incident. The three others joined him on Tuesday.
Their other demands are creating social awareness against rape, forming a special tribunal to punish culprits and ensuring students’ security.
The second-year DU student was allegedly raped in the city’s Kurmitola area on Sunday night.
