The Narcotics Control Bureau (NCB) on Tuesday detained an alleged contraband dealer who has "links" with its probe in the drugs trafficking case pertaining to the death case of actor Sushant Singh Rajput, officials said. The man, who has not been identified, apprehended by the federal anti-narcotics agency is understood to be involved in the supply of narcotics in the high-end party circles of Mumbai. He is expected to be arrested by the NCB on Wednesday after his questioning gave the agency sleuths some "vital leads" into the narcotics case registered against Rajput's live-partner Rhea Chakraborty and others, they said.

The agency last week arrested two men for alleged drug trafficking in the western metropolis and it is understood that the leads against the detained man came after questioning them. A special NCB team from Delhi, headed by deputy director (operations) K P S Malhotra, is camping in the city to take forward this probe. The team also includes agency officers from Mumbai and has been constituted by NCB Director General Rakesh Asthana.
