New Delhi, May 28 -- The Central Bureau of Investigation arrested two more people on Wednesday in the NEET-UG 2026 paper leak case - a Latur-based doctor who allegedly facilitated chemistry questions reaching students, and a Pune physics teacher who obtained leaked questions from an arrested NTA expert - taking the total in custody to 13, as the agency prepares to file itsfirst charge sheet naming three NTA-appointed paper-setters as the key persons behind the breach. As HT reported on Tuesday, the charge sheet will name retired chemistry lecturer PV Kulkarni, botany teacher Manisha Mandhare, and physics teacher Manisha Havaldar - the three NTA experts whose insider access to the question papers has been established. Significantly, the charge sheet will not name any NTA official, even as officials said all aspects of the probe will be "kept open." Dr Manoj Shirure, the Latur-based doctor, "played a key role in facilitating three students, including the son of an accused coaching centre owner, in getting the chemistry questions from the accused PV Kulkarni," the CBI said. The coaching centre owner is Shivraj Raghunath Motegaonkar, who runs Renukai Chemistry Classes in Latur and was arrested last week. His son - not named by the CBI - was questioned last week but has not been arrested. Tejas Harshadkumar Shah, who teaches physics at Dr Abhang Prabhu Medical Academy in Pune, "got the leaked physics questions of NEET-UG 2026 exam from the arrested physics teacher Manisha Havaldar," the agency said, identifying the second new arrest. The charge sheet will consolidate what the investigation has established about the three paper-setters. Kulkarni, one of NTA's chemistry paper-setters, organised special coaching classes at his Pune residence in April 2026 with the help of beauty parlour owner Manisha Waghmare - also arrested - where leaked chemistry questions with answer options and correct answers were dictated to selected students; their handwritten notes matched the actual paper. Mandhare had access to botany and zoology questions as early as April 27 and held parallel classes at her Pune residence, making students note questions in their notebooks. Havaldar, NTA's physics expert, had "complete access" to the physics questions, which she shared with Mandhare and students. The charge sheet's exclusion of NTA officials is notable given that investigators had earlier said the "entire committee that set the paper and other senior officers of NTA are under the scanner." The CBI said its teams are continuing to work to identify "the actual source of the leak before the exam" - the question of how the papers left NTA's secure premises remains unresolved....
