The Narcotics Control Bureau on Tuesday seized drugs worth Rs 2.5 crore after raids at several locations in Mumbai, in what the agency called the “biggest seizure” in the case related to actor Sushant Singh Rajput’s death, PTI reported. The NCB arrested drug supplier Regel Mahakal after the raids.

Mahakal was produced before the Esplanade Court, which sent him to NCB’s custody for two days, ANI reported. He allegedly sold drugs to Anuj Keshwani, another accused in the case. Keshwani was arrested in September.

The NCB recovered hashish, opioids, MDMA or Ecstasy, and crores of rupees in the raids, NDTV reported.

The bureau also detained a man named Azam Sheikh Jumman from Lokhandwala area. The agency took him to his office for questioning. He used to supply drugs to Mahakal, the Hindustan Times reported.

NCB Zonal Director Sameer Wankhede said that the agency could not disclose Mahakal’s links with actor Rhea Chakraborty and her brother Showik Chakraborty, NDTV reported.

Showik Chakraborty was granted bail on December 2, nearly three months after his arrest in the drugs case. Rhea Chakraborty got bail in October. She was accused of procuring drugs for Rajput. The NCB had claimed that she was an “active member of a drug syndicate”.

The NCB had also arrested two alleged drug dealers named Zaid Vilatra and Abdel Basit Parihar in the case. The agency said that Parihar knew Rajput’s house manager Samuel Miranda, who allegedly procured drugs on the instructions of Showik Chakraborty.

Rajput was found dead in his apartment in Mumbai on June 14, in what the Mumbai Police said was a case of suicide. Rajput’s family had accused Rhea Chakraborty of siphoning off his money and drugging him.

Three central agencies – the NCB, the Central Bureau of Investigation and the Enforcement Directorate – were drawn into the investigation. The NCB began an investigation into drugs being used within the film industry after Rajput’s death in June.

The anti-drug agency claimed to have unearthed a close nexus between illegal drug consumption and the film industry. The agency had also questioned actors Deepika Padukone, Shraddha Kapoor and Sara Ali Khan in the case.
