Former Delhi Chief Minister and Aam Aadmi Party chief Arvind Kejriwal said today that the case against senior party leader Satyendar Jain "will be proven fake". His party said the arrest of the former minister is politically motivated and is linked to the coming assembly elections in Punjab. Jain, who spent 18 months in jail in connection with a money laundering case, was arrested this evening. The former water minister has been accused of being involved in the manipulation of a tender process at the Delhi Jal Board.
