The Central Bureau of Investigation (CBI) has uncovered a striking disclosure in the NEET-UG 2026 paper leak case: accused Dinesh Biwal allegedly paid nearly ₹10 lakh to procure a leaked question paper for his son Rishi Biwal — yet Rishi reportedly managed to answer questions worth only 107 marks in the examination. The case, which first surfaced in Rajasthan's Sikar district, has now become one of the most significant disclosures in the CBI's nationwide probe into the examination scam.

The Biwal Family at the Centre

According to investigators, Dinesh Biwal admitted during questioning that he had procured the leaked paper for his son. Despite allegedly having advance access to the question paper, Rishi's performance fell well short of expectations. The case drew further scrutiny after Rishi Biwal's academic marksheet reportedly surfaced online, purportedly showing that he cleared the examination with the assistance of grace marks.

The family had previously attracted public attention in 2025, when Dinesh Biwal posted on social media claiming that five children from his family had successfully cleared the NEET examination. Investigative agencies are now examining whether irregularities may have occurred in that cycle as well, with the CBI reportedly suspecting that leaked papers were used then too.

How the Alleged Network Operated

The CBI believes the operation was part of a larger, organised network spanning multiple states. According to investigators, leaked papers and related files were allegedly circulated through Telegram and WhatsApp groups via a chain of agents and intermediaries. Officials also identified a flat in Sikar that was allegedly being used as a coordination centre for distributing papers and managing communication with candidates.

In some cases, students were allegedly provided compilations of 500–600 'important' or likely questions to gain an unfair advantage. Initial negotiations reportedly took place through social media platforms, with deals allegedly struck with students and parents in exchange for money. Investigators say the network operated across several locations, including Sikar, Gurugram, Nashik, and other parts of Rajasthan.

Scale of the Investigation

The CBI has reportedly identified nearly 150 students who may have links to the network and are currently under scrutiny. Officials informed the court that the case may also involve the destruction of digital evidence, suspicious financial transactions, and possible insider involvement. Some members of the network allegedly acted as couriers, physically delivering leaked material to candidates — a role in which Dinesh Biwal and certain family members are suspected of participating.

Broader Concerns for Exam Integrity

The revelations have reignited serious concerns about the security and transparency of competitive examinations in India. This is not the first time NEET has been embroiled in a paper leak controversy — the examination has faced similar allegations in previous years, raising questions about systemic vulnerabilities in the conduct of high-stakes national tests. The CBI is continuing its efforts to identify the primary source of the leak and the key individuals behind the network.

With the probe expanding across states and the student count under scrutiny rising, the full scale of the alleged racket is yet to be established.
