A special team of the Narcotics Control Bureau (NCB), probing allegations of extortion in the drugs-on-cruise case in which Bollywood superstar Shah Rukh Khan's son Aryan Khan is one of the accused, left for Delhi without recording the statement of witness Prabhakar Sail, who had raised serious charges against Mumbai zonal director Sameer Wankhede and others, an official said.

The five-member team, headed by NCB Deputy Director General (northern region) Gyaneshwar Singh, reached Mumbai on October 27 to record statements after a departmental vigilance probe was ordered against Wankhede and others following Sail's claims that pay off of Rs 25 crore was discussed in connection with the case of which Rs 8 crore was meant for Wankhede.
