Gurugram has emerged as a crucial transit point in the alleged NEET-UG 2026 paper leak network, with investigative agencies now scrutinising the role of a local doctor as the probe widens across multiple states. The development comes after the National Testing Agency (NTA) cancelled the May 3 NEET-UG exam amid allegations of a large-scale paper leak and handed over the case to the CBI for investigation.According to investigation inputs accessed by agencies, the leaked paper trail is believed to have passed through Gurugram before spreading further into Rajasthan and Uttarakhand. Officials suspect duplicate sets of the paper were allegedly prepared in and around Gurugram after a physical copy was leaked from a printing press in Nashik, Maharashtra.Sources said central agencies are examining the possible role of several intermediaries, including medical students, coaching-linked operators, and local contacts. A Gurugram-based doctor is also reportedly under the scanner, though no official arrest or confirmation has been made so far. Indian Medical Association (IMA) Gurugram president Dr Rajesh Kataria said that, while reports mentioning a “doctor from Gurugram” were circulating, no investigating agency had officially contacted the local medical body yet.Rajasthan Special Operations Group (SOG), which first detected irregularities, has identified Sikar as the epicentre of the suspected leak network. Investigators found that a so-called “question bank” or “guess paper” that was circulating before the exam allegedly matched over 100 questions from the actual NEET-UG paper.The probe has traced the circulation trail to an MBBS student from Churu studying in Kerala, who allegedly shared the material with an associate in Sikar on May 1. From there, the paper reportedly spread rapidly through paying guest (PG) accommodations, coaching-linked groups, counsellors, and aspirants across Rajasthan and adjoining states.Investigators suspect the leaked material was distributed through WhatsApp and Telegram channels shortly before the exam. Reports indicate that nearly 150 of the 300 questions in the circulated material allegedly appeared in the actual exam. Authorities are also probing a “question bank” allegedly prepared in Sikar through handwritten compilation methods.The NTA said over 22 lakh candidates had appeared for the exam and clarified that affected students would not need to register again for the re-exam. Fresh admit cards will be issued, while existing exam centres are likely to remain unchanged.The controversy has revived memories of the 2024 NEET issue, when allegations of paper leaks and irregularities triggered nationwide protests and Supreme Court hearings. At that time, the apex court had refused to cancel the entire exam, limiting retests to select centres involving 1,563 candidates.
