The Enforcement Directorate (ED) on Wednesday registered a money laundering case against the now closed NGO, Sewa Sankalp Evam Vikas Samiti, in connection with the alleged sexual assault of 34 girl inmates of a shelter home run by it in Bihar's Muzaffarpur.

The agency will investigate the grants received by it. The properties acquired from the alleged proceeds of crime will also be accounted for.

The agency has initiated the probe under the Prevention of Money Laundering Act following inputs from the local agencies and the CBI.

On a reference from the State government, the CBI had taken over the case from the local police and conducted searches at several locations in the past few weeks.

About a dozen accused persons, including "mastermind" Brajesh Thakur, who allegedly ran the NGO operations through his relatives and associates, have been arrested so far.
