CBI sources said they have evidence indicating that Kumar was one of the officers who had interrogated Ishrat when she was allegedly taken into illegal custody by Gujarat Police before being killed in the staged encounter.
They said the officer was questioned at length with regard to the alleged interrogation and other inputs which suggest his role in the conspiracy leading to the encounter.
The sources also said during questioning, Kumar was evasive and continuously repeated that he did not remember fine points about the incident as it happened nine years ago.
Sources said Kumar, a 1979-batch IPS officer of Manipur- Tripura cadre, had allegedly generated intelligence input that a group of Lashkar terrorists are coming to Ahmedabad to target Gujarat Chief Minister Narendra Modi.
