After the Central Bureau of Investigation (CBI) summoned Delhi Chief Minister Arvind Kejriwal in connection with the ongoing probe into the excise policy of the national capital, Delhi Minister and Aam Aadmi Party (AAP) leader Atishi on Saturday said that the Centre wants to suppress Kejriwal’s voice as he is vocal against the Modi government. Addressing the mediapersons, Atishi said, "CBI has summoned the Delhi CM tomorrow. Why is he being called for an inquiry? Were crores of rupees found in Kejriwal’s house?… Gold biscuits were found. The central agencies have not been able to keep evidence against a single AAP leader or MLA. Now, these investigating agencies are calling Arvind Kejriwal because they want to suppress Kejriwal’s voice."
