The CBI questioned police officer Parikshita Rathod,who first probed the 2004 Ishrat Jahan encounter,in its Gandhinagar office Saturday.
After her probe,Rathod,who is currently posted as deputy commissioner (state intelligence),had concluded that the encounter was not staged.
Sources said many of the witnesses that Rathod had included in her report have reportedly told the CBI they never gave any statement to her.
At the time of the encounter,Rathod was posted with the Detection of Crime Branch in Ahmedabad as assistant commissioner of police (ACP) and was in-charge of womens cell.
Sources said that Gujarat High Court-appointed Special Investigation Team (SIT),which had concluded that the Ishrat Jahan encounter was fake,had found Rathods investigation doubtful.
Based on her investigation,Rathod had filed an affidavit before Gujarat High Court in which she claimed that Ishrat and her friend Javed Sheikh alias Pranesh Pillai had stayed at Tulsi hotel at Bardoli near Surat three days before they were killed on June 15,2004. However,her report was silent on developments between June 12 and June 14.
Rathods report had also suggested that she knew the identity of all the four killed in the encounter,including of Zeeshan Johar and Amjadali Rana who were earlier not identified. SIT had observed that the identification of the four would not have been possible unless they all were in prior custody of the police team.
