Aam Aadmi Party (AAP) leader Sanjay Singh's residence was searched by Enforcement Directorate (ED) officials on Wednesday morning, 4 October.
The latest: ED officials raided the Rajya Sabha MP's house in connection with the Delhi liquor excise policy, according to news agency PTI.
The premises of a few other people linked to the case were also raided, the report added.
Singh's aides were earlier questioned by the ED in connection with the same case.
Kejriwal comes out in support: In a message backing Singh, Delhi Chief Minister Arvind Kejriwal hit out at the Centre and the ED over their investigation into the alleged liquor scam case.
"For the last year we have been seeing, there is noise about alleged liquor scam. More than 1000 raids have been conducted and not a single paise was recovered," the Delhi CM said, adding, "Nothing is going to be found from Sanjay Singh's place too. Elections are coming and they feel (they) are losing, so it appears the last desperate attempt of the losing side," he declared.
