In a hurried press conference, Karnataka Congress leader DK Shivakumar accused investigation agencies like CBI, IT dept of being used by the central government to torment him and his allies. CBI announced that it is conducting raids at five properties. 
However, according to reports, CBI has clarified that there were no search warrants issued against DK Shivakumar and his brother, DK Suresh.
The raids were related to a April , 2017 registered FIR by Anti Corruption Bureau, CBI, Bengaluru in relation to a bank fraud of ₹10 lakh at Corporation Bank, Ramanagara in the post-demonetisation period. 
CBI had registered the FIR back then against B Prakash, chief manager of Ramanagara branch, Karnataka, after they found out that Rs 10 lakh of new 500 and 2000 notes were exchanged without any proper documentation as laid down by the RBI. He had allegedly produced around 250 fake requisition slips to cover up his illegal activities. 
On further investigation, he revealed that he was working on behalf of Karnataka MP, DK Suresh.

This fact was concreted, as CBI dug further only to find out that one of the beneficiaries of this hefty money was DK Shivakumar and his associates, which is why the reported raids were against them.

However, Congress has been seen relentlessly maintaining a single tone and rubbishing the claims.
