Agency sleuths claimed he was arrested after they obtained some "vital leads" into the narcotics case registered against Rajput's live-partner Rhea Chakraborty and others.
The role of Rhea's brother Showik and his purported links with the people nabbed by the NCB are under the scanner of the agency and he and Rajput's manager Samuel Miranda are expected to be summoned for questioning soon, the officials said.
Rajput's manager Samuel Miranda and cook Dipesh Sawant used to collect the contraband and make `joints' (marijuana cigarettes) for the deceased actor, a NCB officer claimed.
'She came yesterday, she came today... we talked to her all day, questioned her. So, I cannot say she is not cooperating. She will come tomorrow too. 'So we are getting her cooperation,' NCB deputy director general (DDG) (south-west region) Mutha Ashok Jain told reporters after the questioning session.
NCB Deputy Director General (south-west region) Mutha Ashok Jain told reporters outside the agency's office later that Rhea will be called again on Monday for questioning and recording of her statement like Sunday.
