Several key leaders hailing from different students unions were taken into preventive custody in the city ahead of the ‘Chalo Secretariat‘, program planned on Monday.

The police swooped down on hostels at Osmania University, Ashoknagar, Dilsukhnagar, Secunderabad and other places and took the student leaders into custody.

The protest call was given demanding the postponement of Group-II and III exams, and the District Selection Committee (DSC) test to recruit teachers, by unemployed youth associations and students unions.
