Dinesh Biwal and his brother Mangilal Biwal were arrested by the Central Bureau of Investigation (CBI) in Jamwa Ramgarh, Jaipur district, Rajasthan, for their alleged involvement in the NEET-UG 2026 exam paper leak. The brothers reportedly acquired a guess paper containing 120 questions from a source in Haryana for ₹30 lakh (approximately $36,000 USD) and sold it to several students in Sikar. The investigation revealed that five members of Dinesh's family had qualified the NEET exam last year, raising suspicions about their success. This led to the CBI's involvement after the Rajasthan Special Operations Group (SOG) initially detained the brothers for questioning. The arrests have ignited a political dispute, with the opposition Congress party accusing the ruling Bharatiya Janata Party (BJP) of shielding the culprits. Former Chief Minister Ashok Gehlot criticized the BJP, questioning their delay in filing a First Information Report (FIR) regarding the case. Dinesh Biwal, who has been associated with the BJP's youth wing, has also been linked to local political figures, further complicating the situation.
