The Enforcement Directorate has written to Kolkata Police seeking details of investigation officer Manoj Kumar. An assistant director of the ED has been taken off investigations into the Rose Valley chit fund scam and two other cases after a video clip, purportedly showing him checking into a New Delhi hotel with the wife of a prime accused in the Rose Valley case, was aired on TV channels in Kolkata.<br/><br/>ED sources said orders have been issued to suspend the officer, Manoj Kumar, and start a probe to ascertain if his links impacted investigation in the case. <br/><br/>Sources said another investigation officer (IO) has replaced Kumar. Sources said the video clip, reportedly sourced from West Bengal police, shows Manoj Kumar and the woman checking into a hotel in Sunder Nagar after they travelled from Kolkata to New Delhi on 18th of this month. <br/><br/>A card belonging to an accused in a case being probed by the ED was used for payment at the hotel, sources said. West Bengal police, sources said, stumbled upon the footage while on the trail of hawala operators. <br/><br/>The arrested operators led police to a chartered accountant who, sources said, had a file named "Madam Rose Valley" on his computer. Joint CP (Crime) Vishal Garg said a haul of 1.42 crore rupees in demonetised notes from central Kolkata led them to the chartered accountant's firm. ED sources confirmed they had received a report on the officer from Kolkata police.
