Aam Aadmi Party (AAP) Rajya Sabha MP Sanjay Singh in connection with its ongoing money laundering probe in the Delhi liquor policy scandal.
Singh was arrested after the federal agency carried out searches at his residence on Wednesday morning. Singh was arrested on grounds of alleged non-cooperation with the probe agency and giving evasive replies.
Singh's name is mentioned in the charge sheet filed by the agency in the liquor policy scandal.
Delhi's former deputy chief minister Manish Sisodia is the prime accused in the case. This is the third big arrest of an AAP leader by the federal agency in the liquor scandal after Sisodia and Satyendar Jain.
Sisodia was taken into custody by the ED on March 9 from Tihar jail after he was initially arrested by the CBI on February 26, this year.
Singh's staff members and those linked to him were earlier questioned by the ED.
Some other premises of people linked to Singh were also searched, said people in the know.
The AAP leader, who has been arrested under relevant provisions of the Prevention of Money Laundering Act (PMLA), will be produced before a local court on Thursday. The agency will seek custodial interrogation of Singh.
The Central Bureau of Investigation had booked Sisodia and 15 others last August on charges of corruption, criminal conspiracy, falsification of accounts and undue advantage in connection with the liquor policy.
The agency had also registered a first information report against 10 people and their associates, who obtained licences to sell liquor following a reference from the Union home ministry, which sought a probe into «irregularities» in the Delhi excise policy.
