The Narcotics Control Bureau has suspended two of its officials, who were part of a probe into the cruise drugs case, after a departmental inquiry against them in another case, an NCB official said on Thursday.

Two duo - superintendent Vishwa Vijay Singh and intelligence officer Ashish Ranjan Prasad - had allegedly helped an accused in another drugs case secure bail, he said.

An internal inquiry was conducted against the two officials and after the completion of the probe, they were placed under suspension, the official said.

The director general of NCB, S N Pradhan, however, said, “Their suspension has nothing to do with the Aryan Khan probe but for procedural and vigilance lapses in a separate matter”. “The decision to suspend them has been taken on the basis of a report submitted by zonal director and regional director (of Mumbai),” the DG said.

Pradhan added that the “vigilance enquiry in Cordelia case is still continuing”.

The narcotics enforcement agency didn’t elaborate on the exact charges against Singh and Prasad and the case in which they have been handed the suspension.

In October last year, a team of the NCB's Mumbai zone had raided a Goa-bound cruise ship and claimed to have seized drugs onboard. Bollywood actor Shah Rukh Khan's son Aryan Khan and some others are accused in that case.
