Digvijaya Singh, who met Home Minister Sushilkumar Shinde, said confusing statements were being made by different security agencies - the Central Bureau of Investigation (CBI), the Intelligence Bureau (IB) and the National Investigation Agency (NIA).
"Unofficial, selective leaks in the Ishrat Jahan case are creating confusion in the public mind, and that is not in the interest of internal security," Singh told reporters after his meeting with Shinde.
"The home ministry must clarify whether Headley told the team which went to the United States to interrogate him that Ishrat Jahan had terrorist links," he said.
The call from Singh came as reports claimed that Headley had told the NIA during his interrogation in the US that a terrorist plan, plotted by the Lashkar-e-Toiba (LeT) had failed after the death of Ishrat Jahan and the three men who accompanied her.
