The Bihar Public Service Commission (BPSC) cancelled its preliminary examination at the Bapu Pariksha Parisar centre in Patna due to disruption by unruly candidates on December 13. A ruckus, including allegations of a question paper leak, led to the death of an additional superintendent and the unconsciousness of a female candidate. BPSC has identified 30-40 disruptive aspirants, who will be debarred from future exams. The examination will be rescheduled for around 6,500 affected students.
