The letter, which has been discovered by the CBI from Shehla's personal documents, claimed that MP CM, Shivraj Singh had spent Rs 5 lakh for Advani's personal visit to Panchmarhi.
Media reports, on the information based on CBI source, informed that a state plane was used for the to and fro journey of Advani from New Delhi to Bhopal and the state helicopter was provided for the journey from Bhopal to Panchmarhi and back.
The letter reportedly was written just two weeks before her murder in Bhopal and it (letter) was sent to the Chief Vigilance Commissioner (CVC). Shehla was brutally assassinated when Anna Hazare was holding his fast in Delhi's Ramlila Maidan. A BJP MP, Tarun Vijay and a BJP MLA have also come under the investigation scanner over the RTI activist's murder.
