NCP's Maharashtra unit chief and state minister Jayant Patil has said that his party colleague Nawab Malik may have some concrete evidence against NCB's Mumbai zonal director Sameer Wankhede, without which he would not have made statements against the officer.

Over the last few days, Malik has been criticising Wankhede, who had supervised a raid on a cruise liner off the Mumbai coast earlier this month that led to the alleged recovery of drugs and arrest of superstar Shah Rukh Khan's son Aryan. Two days back, the NCP leader had dubbed the officer as "bogus" and asserted that once "proof" against him is out, he cannot remain in government service for even one day.
