Role in the Sushant Singh Rajput Case
The tragic death of Sushant Singh Rajput on June 14, 2020, initially ruled as a suicide, sparked widespread controversy, with allegations of mishandling the investigation by the Mumbai Police. Following a request by Rajput’s father, KK Singh, the case was transferred to the CBI by the Supreme Court of India on August 19, 2020. The CBI formed an SIT to investigate the matter, with Nupur Prasad at the helm.
Under her leadership, the SIT was divided into three teams:
- Team 1: Collected crucial documents and forensic evidence, including crime scene photos, postmortem reports, and the Mumbai Police forensic report.
- Team 2: Interrogated key individuals, including Rhea Chakraborty (Sushant’s girlfriend), her family, and Sushant’s flatmate Siddharth Pithani.
- Team 3: Investigated possible professional rivalries and other angles that could explain the circumstances surrounding Rajput’s death.
Nupur’s approach during the investigation was calm, thorough, and methodical. She personally interrogated Rhea Chakraborty for several hours, handling the questioning with firmness and professionalism. When Rhea raised her voice in frustration, Nupur responded firmly yet calmly, saying, “If you are innocent, you have to prove it by cooperating with the investigation.” Her balanced yet strict interrogation style was widely admired, especially in handling sensitive cases and female suspects. The CBI has now officially submitted a closure report in the high-profile suicide case.
