The NEET-UG 2026 examination leak investigation has intensified following the arrest of Shivraj Motegaonkar, founder of RCC Classes in Latur, Maharashtra, India, on May 18. This development came after parents of a NEET aspirant claimed that 43 out of the 45 chemistry questions in the exam matched those in a 'guess paper' distributed by RCC. Investigators suspect that the leak may have originated from P V Kulkarni, a retired chemistry professor with ties to the National Testing Agency (NTA), who had access to four different chemistry paper sets before one was finalized for the exam. Sources indicate that nearly 133 questions from all sets appeared in RCC's guess paper, raising serious concerns about the integrity of the examination process. The CBI's investigation revealed that Motegaonkar allegedly received the leaked questions on April 23, 2026, approximately ten days before the exam. The situation escalated when a video surfaced of Motegaonkar discussing how questions from RCC's materials appeared in the actual NEET exam, prompting further scrutiny and a complaint to the police. The investigation continues as multiple teams question individuals and search for evidence in Latur and surrounding areas.
