CBI sources said the officer posted in Chandigarh is under inquiry for allegedly leaking information about the operation to some people who conveyed it to the wife of Kumar in Mumbai.
Wasting no time, Bansal's wife took the help of a railway inspector to move valuables and other important documents from her residence to safe place. However, they emphasised that the officer is only under suspicion.
The sources said the agency is also looking into family relations of the officer to understand whether the alleged leak was actually intended to benefit some of the accused or was it an inadvertent slip on his part.
The role of a senior officer of the Railway Police Force has also come under CBI lens since he had instructed an inspector of his force to collect the bag given by Kumar's wife and hide it, the sources said. They said the CBI has questioned an RPF inspector who told the agency that he acted on the instructions of a senior officer.
The sources said the inspector had hidden the bag at his friend's place in a suburb in Mumbai from where it was recovered by the CBI during a search operation on May 6, three days after the arrest of Kumar.
Kumar, along with Singla, was arrested on May 3 on the allegations that the Railway Board member had struck a deal of Rs 10 crore bribe to get posting of choice in the board and paid Rs 90 lakh as part payment.
