Telangana BJP leader Ram Chander Rao has said that the arrest of businessman Arun Ramchandra Pillai shows how the so-called South lobby - that is close to the BRS leadership - is involved in the Delhi liquor scam. He said that earlier also, some people close to K Kavitha have been arrested in the scam. He said that nobody should interfere in the probe and investigating agencies should be allowed a free hand.
