The CBI probing the case has decided to question some IB officers to understand the basis of the warning and the source of inputs, the agency sources said.
CBI sources said a Special Investigation Team constituted by Gujarat High Court had recommended probe into the role of the Intelligence Bureau officials.
They said CBI also in its probe has found some indications which require the role of IB officials to be probed.
They said CBI has also analysed intelligence input generated from the IB here cautioning the state police about Lashkar-e-Taiba's plan to attack BJP leaders L K Advani, Narendra Modi and VHP leader Praveen Togadia.
The sources who refused to give the names of the IB officers said the people who were handling VIP security wing of the snooping agency will be examined to understand the basis of the alert issued in 2004.
The agency will also investigate the inputs received by Gujarat Police that led to identification of a blue car, in which Ishrat Jahan was travelling, as the car in which the alleged terrorists were travelling, they said.
The CBI on the instruction of Gujarat High Court took over the probe of the alleged fake encounter in which 19-year-old Ishrat, Javed Sheikh alias Pranesh Pillai, Amjad Ali Rana and Zeeshan Johar were killed in Ahmedabad on June 15, 2004 by Crime Branch team led by DIG D G Vanzara. (more)
