T News, a news channel owned by family members of Telangana chief minister K Chandrasekhar Rao, says ACB is gearing up to slap notices on Andhra Pradesh chief minister N Chandrababu Naidu and a couple of Rajya Sabha members  in cash-for-vote case. According to the news channel, which has access to key information in government and ACB, notices would be issued once the investigating agency receives the report about the veracity of audio tapes which contained purported telephonic conversation between Chandrababu Naidu and nominated MLA from Telangana Elvis Stephenson, from Forensic Sciences Laboratory. The contents of the report will be crucial as it would form the basis for Revanth Reddy’s bail and arrest of some more people. The report is expected today or tomorrow, T New said.
