The Akhil Bharatiya Vidyarthi Parishad (ABVP) has demanded that the State government initiate disciplinary action against officials of the Pre-University Board responsible for the leak of two II PU question papers.

Even as the authorities postponed the Physics examination on Thursday following the question paper leak, students, led by the ABVP office-bearers, took out a procession in the city and formed a human chain at the Sardar Vallabhbhai Patel Chowk for more than 30 minutes.
