The Enforcement Directorate on Friday summoned Himachal Pradesh chief minister Virbhadra Singh and some of his associates in connection with a money laundering case. They are to appear in Delhi in the first week of December. The summons have been issued under the provisions of the Prevention of Money Laundering Act, which necessitate Singh's presence before the investigators, reported PTI.

On November 15, the directorate had registered a money laundering case against him based on a complaint by the Central Bureau of Investigation. The CBI is investigating corruption charges against him for allegedly amassing disproportionate wealth of Rs 6.1 crore during 2009-2011 during his term as Union minister of steel.

Investigators say they have gathered some important documents and detected the suspected “proceeds of crime” that Singh and his associates used to channel illegal funds, PTI reported. ED teams had also conducted searches in this case last week in three states of Delhi, Maharashtra and West Bengal. CBI had also carried out searches at various properties belonging to Singh and his family immediately after filing the FIR, an act that the Congress party had then called “highly vindictive”.
