Delhi Chief Minister Arvind Kejriwal was questioned for nearly nine hours by the Central Bureau of Investigation (CBI) today in the liquor policy case. He was questioned as a witness in the case which investigators said involved corruption in framing the policy to benefit a liquor lobby. He hasn't been summoned for further questioning by the central agency so far. "The CBI asked me a total of 56 questions. Everything is fake. The case is fake. I am convinced they don't have anything on us, not a single piece of evidence," Mr Kejriwal told reporters after reaching home from the CBI headquarters near central Delhi's Lodhi Road.
