Appearing for the CBI, Attorney General K K Venugopal alleged that the special investigation team (SIT) of the West Bengal police headed by Kumar was not handing over the complete documents.
Some of the documents submitted by them were "doctored" and the SIT had not even sent the laptops and phones seized from the main accused, Sudipta Sen, in the case, Venugopal alleged. In its affidavit submitted before the court, the probe agency also said that it had in its investigation found incriminating evidence against senior police officials, as well as politicians, of the state.
Terming it a breakdown of constitutional machinery, the CBI's lawyer said that the officers who had gone to probe Kumar were forcibly pushed inside buses and manhandled by police officials of the state.
