The Central Bureau of Investigation (CBI) has concluded that no government official — including NTA office bearers — was involved in the NEET UG 2026 paper leak, with investigators determining that the question papers were taken out of the National Testing Agency by the teachers it had contracted to set them, people familiar with the development said.Accused Prahalad Kulkarni being brought to Rouse Avenue Court in connection with the NEET-UG 2026 paper leak case, (ANI Video Grab)The agency will file its charge sheet this month. All 13 persons arrested in the case are private individuals, including three teachers allegedly at the heart of the leaks — PV Kulkarni for Chemistry, Manisha Mandhare for Biology, and Manisha Havaldar for Physics. “In the past two months, we have not come across any evidence that suggests involvement of any government officer, including NTA office bearers, in the paper leak.
