The Central Bureau of Investigation (CBI), has filed chargsheet in the NEET UG paper leak case before the Delhi Court. CBI investigation has revealed that
accused used incriminating WhatsApp, Telegram chats, and scanned question papers on phone which is yet to be found by the agency. The federal probing agency has also mentioned that the Delhi University (DU) expert panel and other investigations confirmed an exceptionally high percentage of matches between the leaked materials and the NTA's official master sets. CBI investigation details accessed by Times Now reveal fresh details from the NEET-UG 2026 paper leak investigation. As per the documents accessed, on May 12, 2026, one of the accused - Mangilal Khatik - was examined by the Rajasthan Special Operations Group (SOG). Investigators found incriminating WhatsApp and Telegram chats linked to the case on his mobile phone. WhatsApp chats between Mangilal Khatik and another accused, Yash Yadav, were recorded and formally printed in the presence of independent witnesses. The CBI has taken 28 pages of WhatsApp chat printouts as part of the evidence. Meanwhile, the Telegram chats between the two allegedly contained scanned copies of question papers related to NEET-UG 2026. The documents mention three files: "NV 1 2000 (1).pdf”, “NV 2 2000.pdf”, and “Physics.pdf”. The crucial thing here to note is that these documents were leaked at 1 AM on April 29 - which is three days before the NEET UG exam. CBI has also mentioned the relevant Telegram profile-chat pages, with three pages of chat taken on record. The accused’s phone was subsequently subjected to forensic imaging using "Cellebrite UFED" by the CBI’s Netra Lab in New Delhi. The forensic exercise was carried out on a Samsung Galaxy A34 5G phone, according to the document.
