"Rubabuddin Shaikh has sought probe of telephone calls between the office of Chief Minister and senior IPS officers under Sec 173 (8) of the CrPC," his lawyer Mukul Sinha said. The section allows further investigation after charge sheet is filed.
Sohrabuddin was killed in an alleged fake encounter by Gujarat police in November 2005.
"The telephone records produced by CID (Gujarat) in the case of Tulsiram Prajapati along with the charge sheet reveals that at least two accused, namely Amit Shah (then Minister of State for Home) and IPS officer Rajkumar Pandian, were in constant touch with the office of Chief Minister of Gujarat throughout December 2006," Rubabuddin's application to the CBI director states.
Shah, the key accused in Soharabuddin case, also figures as kingpin of the conspiracy in the case related to subsequent fake encounter of Sohrabuddin's aide Prajapati.
Shaikh was killed on November 26, 2005 in Ahmedabad. Prajapati was the sole witness to his kidnapping and killing, according to CBI. Prajapati was killed in another encounter on December 28, 2006.
