Jaipur/Pune/Nashik, May 14 -- The Central Bureau of Investigation arrested five people on Wednesday in the NEET-UG 2026 paper leak case, including the man investigators believe first couriered the question paper into the network - a BAMS graduate and practising doctor from Maharashtra's Ahilyanagar who was also doing medical college admissions counselling - and a Sikar-based family that bought the paper for Rs.15 lakh and sold it onward for Rs.30 lakh. Two others were detained by state police on the CBI's behalf, as investigators mapped a complete financial chain running from Maharashtra through Haryana to Rajasthan's coaching belt. Dhananjay Lokhande, 26, from Rahuri tehsil in Ahilyanagar, is the earliest known node in the chain of a leak that will now require close to 2.3 million medical college aspirants to retake a test that most spend months, if not years, preparing for. Lokhande, a BAMS graduate from Mangaluru practising medicine in his home district, also did counselling related to medical college admissions - a proximity to the NEET ecosystem that investigators are examining closely. He allegedly couriered the so-called "guess paper" to Shubham Khairnar, who paid Rs.10 lakh for it. He was picked up from his village in the early hours of Wednesday following a CBI tip-off. The five formally arrested by CBI are Lokhande, Yash Yadav from Gurugram, Dinesh Biwal, his brother Mangilal Biwal and Mangilal's son Vikas from Jaipur's Jamwa Ramgarh, and Shubham Khairnar from Nashik. Khairnar was detained by Maharashtra police on Tuesday and whose custody has since been transferred to the agency. The Biwal brothers and Vikas had been detained by the Rajasthan SOG on Monday for questioning; CBI formally arrested them on Wednesday morning. Manisha Waghmare from Pune too was detained by state police on the CBI's behalf. All are being questioned by the CBI in Jaipur; Khairnar is being brought to Delhi for further interrogation. "Several other suspects are currently being examined," a CBI spokesperson said. "The agency has formed multiple teams to investigate all aspects. Key persons involved in sharing the question paper are being traced. The CBI is pursuing all leads through technical and forensic analysis."...
