Karti Chidambaram met his father P Chidambaram at Tihar jail on Wednesday and said that the former Union Minister is in good spirits. Karti also said that the probe agencies are conducting a bogus investigation and accused the Modi government of indulging in vendetta politics again. This even as the Enforcement Directorate questioned Chidambaram and even arrested him inside Tihar jail in connection with the money laundering probe in the INX media case.
