The Central Bureau of Investigation (CBI) has made another arrest in the alleged NEET-UG paper leak case from Jharkhand's Dhanbad. Aman Singh was arrested following intelligence inputs about a Jharkhand-based module allegedly involved in the alleged paper leak, officials said, news agency PTI reported. The CBI is investigating the alleged NEET-UG irregularities on May 5 — a nationwide entrance exam conducted by the National Testing Agency (NTA) for admission in UG medical programmes. The agency had earlier arrested principal and vice principal of Hazaribagh-based Oasis school in the case, and two other people who allegedly provided safe premises to NEET candidates where burnt question papers were recovered by Bihar Police, the officials said. The CBI has registered six FIRs in the case. The FIR from Bihar pertains to leakage of paper while remaining from Gujarat and Rajasthan pertains to impersonation of candidates and cheating. The agency's own FIR on a reference from the Union Education Ministry pertains to a "comprehensive investigation" into alleged irregularities in the medical entrance examination. With PTI inputs
