In yet another blow for the Aam Aadmi Party, the Enforcement Directorate has arrested its Rajya Sabha MP, Sanjay Singh, in a money laundering case linked to the investigation into the Delhi liquor policy. Searches were being conducted at the Delhi residence of the MP since early on Wednesday morning. This is the third major arrest from the party. Delhi Health Minister Satyendar Jain was arrested in May last year on charges of laundering money through four companies that were allegedly linked to him.
