The NEET-UG 2026 paper leak investigation has intensified after the Central Bureau of Investigation (CBI) arrested Pune-based senior botany teacher Manisha Gurunath Mandhare, alleging she played a central role in the conspiracy. The accused, who was reportedly appointed as a subject expert by the National Testing Agency (NTA), is now in CBI custody in Delhi following a court order from the Rouse Avenue Court.

According to investigators, Mandhare is suspected of being one of the key masterminds behind the alleged leak of the biology question paper. The CBI claims that her official position within the exam preparation process gave her access to highly sensitive and confidential examination material, which was allegedly misused.

Mandhare, a senior faculty member from Pune, is said to have been involved in the NEET examination process for several years as a botany expert. Officials believe that her academic role allowed her access to question paper preparation, translation, and verification processes. This access, according to the agency, became a critical link in the alleged leak network.

The CBI further alleges that Mandhare worked closely with other accused individuals, including professor P.V. Kulkarni and consultant Manisha Waghmare, who was arrested earlier in the week. Investigators claim that this group formed a coordinated network to identify potential candidates and distribute leaked exam content before the official examination date.

One of the most serious allegations against Mandhare is that she conducted special coaching sessions in Pune ahead of the NEET-UG 2026 exam. During these sessions, she allegedly discussed important biology questions that were expected to appear in the exam. Students were reportedly instructed to note down these questions and highlight related topics from their textbooks for preparation.

According to the CBI, a significant number of questions discussed in these sessions matched the actual questions that appeared in the NEET biology paper conducted on May 3, 2026. This alleged similarity has become a key part of the investigation, strengthening suspicions of prior access to the question paper.

The agency also claims that Mandhare and her associates were involved in identifying and recruiting candidates for the alleged leak operation. These candidates were allegedly provided with confidential study material under the guise of advanced preparation classes.

Officials say that Mandhare was not only involved in academic roles but also had access to sensitive examination workflows due to her position as an NTA-appointed expert. This dual responsibility, investigators argue, created a potential security loophole that may have been exploited.

After her arrest, Mandhare was produced before the Rouse Avenue Court in Delhi, where the CBI sought custodial interrogation. The court granted 14 days of custody, stating that the seriousness of the allegations required deeper investigation and cross-state interrogation.

The CBI has stated that the investigation is ongoing and expanding across multiple states, including Maharashtra and Delhi. Authorities are currently analyzing digital evidence, communication records, financial transactions, and coaching-related activities linked to the accused and other suspects.

The NEET paper leak case has once again raised serious concerns about the security of national-level competitive examinations in India. NEET, being one of the most important entrance tests for medical education, directly impacts the future of thousands of students every year.

Experts believe that if individuals involved in question paper preparation are found to be misusing their positions, it points to systemic vulnerabilities in the exam conduction process. This has led to renewed demands for stricter monitoring, stronger encryption systems, and better background verification of exam personnel.

Meanwhile, students and parents across the country have expressed concern and frustration over repeated allegations of exam irregularities. For many aspirants, NEET represents years of preparation, and any compromise in exam integrity severely impacts trust in the system.

The CBI is now expected to interrogate Mandhare further to trace the full network behind the alleged leak. Investigators are also exploring whether the leaked material was distributed through coaching centers, private academic groups, or online platforms.

As the probe continues, Manisha Gurunath Mandhare remains in custody, and more arrests are likely as the investigation progresses. The case is emerging as one of the most significant exam fraud investigations in recent years, with potential long-term implications for how national entrance exams are conducted and monitored in India.
