The Central Government on Friday directed the competent authority to take appropriate action against the former Narcotics Control Bureau (NCB) official Sameer Wankhede for his shoddy investigation into the cruise drug bust case involving Aryan Khan, the son of Bollywood superstar Shah Rukh Khan.

The Centre's action came soon after the NCB gave a clean chit to Aryan Khan and five others and has not filed any chargesheet against them citing the lack of evidence.
