The agency had carried out searches at multiple locations after the charge of the case was given to new Investigating officer Mohit Gupta, they said.
Justifying the transfer, the CBI pinned the blame on Mishra for keeping the preliminary enquiry pending without any reasons, they said.
The officials said after review some time ago, the PE was sped up and was converted into a regular case.
Immediately after the registration of the case, the searches were proposed, they said.
However, it was suspected that there was a possibility of information regarding searches being leaked, the officials claimed.
“A discreet inquiry was conducted and role of Sudhanshu Dhar Mishra was strongly suspected. Hence he has been transferred pending detailed inquiry in the matter, being serious,” he said.
