NCP leader and senior Maharashtra Minister Nawab Malik has claimed that Narcotics Control Bureau's (NCB) Mumbai zonal director Sameer Wankhede was the kingpin of the drug racket running in Mumbai. Addressing the media on Monday morning, Malik claimed that former Maharashtra Chief Minister Devendra Fadnavis was behind the transfer of Sameer Wankhede to the NCB. Meanwhile, Devendra Fadnavis has hit back at the allegations, saying that he has evidence of Nawab Malik's relations with the Underworld and will expose him once Diwali is over.
