Manoj Kumar, an assistant director of the Enforcement Directorate (ED), has been debarred from 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. ED sources said orders have been issued to suspend the officer, and start a probe to ascertain if his links impacted investigation in the case. 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 January 18. A card belonging to an accused in a case being probed by the ED was used for payment at the hotel, sources said.
