Former Narcotics Control Bureau (NCB) Mumbai zonal director Sameer Wankhede has alleged that then Deputy Director of the NCB Gyaneshwar Singh humiliated and harassed him during an inquiry as Wankhede belongs to a backward community.

The CBI had summoned Wankhede for questioning in Mumbai on Thursday in connection with alleged demand of Rs 25 crore from superstar Shah Rukh Khan for not implicating his son Aryan Khan in the Cordelia cruise drug bust case, but Wankhede did not appear before the agency`s team.
