The Enforcement Directorate arrested Rajya Sabha MP Sanjay Singh on Wednesday, hours after raiding his home in Delhi over a money laundering case linked to the liquor policy case that haunts the ruling Aam Aadmi Party. He joins Chief Minister Arvind Kejriwal, his former deputy Manish Sisodia, Telangana politician K Kavitha, and others in being raided, questioned or arrested, or all three, in connection with alleged corruption in the Delhi government's now-withdrawn liquor policy.
