Dehradun, Sept. 26 -- Protests over the alleged leak of the UKSSSC graduate-level written examination continued on Thursday as agitating youth camping at Dehradun's Parade Ground declared they would not call off their agitation until a CBI investigation is ordered. Uttarakhand Berozgar Sangh president Ram Kandwal said the protesters have three main demands. "An immediate recommendation for a CBI probe, cancellation of the tainted graduate-level exam and conduct of a fresh test within a month, and the resignation of the UKSSSC chairman. Until these demands are met, our protests will continue", he said Amid the controversy, the state government also suspended Sector Magistrate KN Tiwari, posted at Adarsh Bal Sadan Inter College, Bahadurpur Jat, where irregularities were reported on the day of the exam. Tiwari, who is also Project Director at the District Rural Development Agency (DRDA), Haridwar, was found prima facie guilty of negligence in duty during the conduct of the exam, officials said. Meanwhile, the Special Investigation Team (SIT) constituted to probe the case has urged students, candidates, and the public to share any information related to the leak. The SIT, led by SP Rishikesh, under the supervision of a retired high court judge, has statewide jurisdiction. Information can be shared at spdehatddn@ gmail.com or via WhatsApp at +91 9027083022. Police on Wednesday arrested the alleged mastermind Khalid (35), who appeared as a candidate at a Haridwar centre and photographed pages of the question paper during Sunday's exam. The images were sent to his sister Sabia, who transmitted them to Suman, an assistant professor in Tehri Garhwal, for answers. ....
