Deputy Director-General Sanjay Kumar Singh, heading the Special Investigation Team (SIT) of Narcotics Control Bureau headquarters, said that a fair and impartial investigation will be done in the six cases taken over by his team from NCB Mumbai, including the drugs-on-cruise case.

"We have started the investigation, we will do whatever a fair and impartial investigation demands," said Mr Singh. The SIT arrived in Mumbai today. Earlier, speaking to media persons at Mumbai airport, he said, "We have taken over a group of 6 cases. He (Sameer Wankhede) is the zonal director of Mumbai, we will definitely take his assistance in the investigation." Speaking to ANI over the phone, an NCB official said that Sameer Wankhede is an Officer of Zonal Director Rank which is equivalent to the rank of a Deputy Inspector General (DIG) and such a senior officer does not become the investigating officer of any case.
