Bengaluru, Aug. 31 -- The Karnataka CID has arrested Indian Administrative Service (IAS) officer Gyanendra Kumar Gangwar in connection with alleged irregularities in the Karnataka Public Service Commission (KPSC) examination for 400 veterinary officer posts, officials said. Gangwar, a former KPSC examination controller, was taken into custody late Saturday night after several hours of questioning in a probe into alleged question paper leakage, OMR sheet manipulation and marks tampering. Investigators found inconsistencies in his statements and felt he was not cooperating with the inquiry. He is expected to be produced before a magistrate on Sunday, officials aware of the development said.

He was booked under relevant sections of the Bharatiya Nyaya Sanhita (BNS) and Section 10 of the Karnataka Public Examination (Measures for Prevention of Corruption & Unfair Means in Recruitment) Act. The government transferred the case to the Criminal Investigation Department (CID) on July 28 after two cases were registered at the Vidhana Soudha police station. The complaint was filed by veterinarian Manjunath against suspended former KPSC chairman Shivashankarappa S Sahukara and others.

The complaint raised further questions about the conduct of candidates before the examination. Some candidates alleged that shortlisted aspirants switched off their mobile phones before or on the examination days and stayed at hotels and resorts outside Karnataka, where intermediaries allegedly provided them with the questions. Manjunath also questioned the authenticity of OMR answer sheets. He alleged that candidates who had left several questions unanswered nevertheless secured high marks....
