According to the Central Bureau of Investigation (CBI), she had authorised access to the Biology question paper and is accused of leaking confidential exam content to selected candidates before the medical entrance examination. Investigators allege that she conducted special coaching sessions at her Pune residence, where Biology questions that later appeared in the actual NEET UG 2026 paper were reportedly discussed with students.How the Alleged NEET Biology Paper Leak Was Carried OutThe CBI stated that Mandhare allegedly worked with Pune-based consultant Manisha Wagmare, who was arrested earlier this week, to identify and recruit prospective NEET candidates.Investigators claim that in April 2026, Mandhare conducted special coaching sessions at her residence in Pune. During these classes, she reportedly dictated Biology questions expected to appear in the NEET UG 2026 examination.Students attending the sessions were allegedly instructed to write down the questions in notebooks and highlight corresponding topics in their textbooks.The agency further claimed that a significant number of the questions discussed during these classes matched the actual NEET UG 2026 Biology paper conducted on 3 May before the examination was later cancelled.NTA Expert Under Investigation for Breach of Examination ConfidentialityThe arrest has intensified scrutiny over the security mechanisms followed by the National Testing Agency during the preparation and handling of examination papers.CBI officials said Mandhare had been entrusted with confidential responsibilities as an NTA-appointed expert, giving her authorised access to sensitive examination material.The agency is now investigating whether additional insiders within the examination system were involved in the alleged leak network.Multiple Raids Conducted Across IndiaOver the past 24 hours, the CBI conducted searches at six locations across the country as part of the widening investigation.Officials said the raids led to the seizure of several incriminating documents, laptops, mobile phones and bank records.
