The case has been registered under the Official Secrets Act (OSA) in connection with the recovery of confidential Defence Ministry documents from his house in South Delhi's Defence Colony.
The FIR was registered on Friday by Colonel Puneet Ahuja, an officer posted in the Ministry of Defence, alleging that the Ministry is the custodian of the classified documents that were recovered in the raid.
According to the FIR the documents pertain to policy planning and Force Development branch of the Defence Ministry.
Bhandari is already under the scanner of the Enforcement Directorate (ED) and Income-Tax (I-T) Department for allegedly holding a 'benami' property in London.
The IT Department had been carrying out an investigation against Bhandari and the OIS Group in connection with a tax evasion case.
Earlier in June, the IT Department carried out searches on two Bengaluru-based business premises associated with defence consultant Sanjay Bhandari, who is under investigation for ascertaining the sources of about Rs.70 crore received by his companies between 2009 and 2014.
