The Central Bureau of Investigation (CBI) is broadening its probe into the NEET-UG 2026 paper leak following the arrest of a second insider, Manisha Gurunath Mandhare, a botany teacher from Pune. Mandhare allegedly leaked exam questions weeks before the test, having been appointed to the National Testing Agency's (NTA) paper-setting committee. Her arrest follows that of retired chemistry lecturer PV Kulkarni, identified as a 'kingpin' in the operation. The CBI has revealed that two sets of leaked papers were found, one handwritten and another typed, with Mandhare and Kulkarni conducting special coaching sessions where they disclosed exam questions to select students. The investigation has led to the arrest of nine individuals across five states, including co-accused Manisha Waghmare, who facilitated student access to Mandhare's classes. The leaked material reportedly circulated through middlemen and Telegram groups, with one PDF containing approximately 500-600 questions. Following the leak, the May 3 NEET examination was canceled, and a re-test is scheduled for June 21. The CBI remains committed to a thorough investigation to uncover all involved.
