Stepping up its attack on the Narcotics Control Bureau (NCB), the NCP on Friday alleged that the anti-drug agency let off two persons after a raid on a cruise ship off Mumbai coast recently, with one of them being the brother-in-law of a "high-profile" BJP leader.

Targeting NCB's zonal director Sameer Wankhede, NCP spokesperson and Maharashtra minister Nawab Malik also raised questions over the conduct of the agency officials.
