Protesting non-fulfilment of their longstanding demands, students of the Brahmapur Nursing College staged a dharna in front of the college again on Monday.The students had been demanding dismissal of the college chairman and the accountant. They were attending classes and clinical duties by wearing black badges.Though the college authority had sought 15 days to fulfill our demands, no step has been taken yet. Even talks with Deputy DMET Sikata Nanda didn’t yield any positive result, rued the students. They threatened to continue stir and boycott internal examination if their demands are not met soon.
