Narcotics Control Bureau (NCB) zonal director Sameer Wankhede on Tuesday evening met Mumbai police commissioner Hemant Nagrale here, an official said. The meeting between Wankhede, who is facing a slew of allegations, and Nagrale lasted for around 25 minutes, he said. However, what transpired between the two officers was not disclosed.

"It was a routine meeting. Such meetings with senior officers are held regularly," the official said. A special investigation team of the Mumbai police is probing allegations of extortion bid by some NCB officials in the drugs-on-cruise case in which Bollywood superstar Shah Rukh Khan's son Aryan is one of the accused. The Narcotics Control Bureau (NCB) is separately conducting a vigilance inquiry into the alleged extortion bid by agency officials, including Wankhede, for letting off Aryan Khan in the case.
