The CBI has registered an FIR against former deputy chief minister of Manish Sisodia and others in connection with the Delhi Government’s Feedback Unit (FBU), which was allegedly doing political snooping, officers said on Thursday. Sisodia was earlier arrested by the CBI in the Delhi excise policy case and is behind bars in an Enforcement Directorate case.

The CBI said that Kejriwal moved a proposal to set up FBU in a Cabinet meeting in 2015, but no agenda note was circulated. No sanction from the Lt Governor was taken for appointments. The unit started functioning in 2016 with a provision of R1 crore for secret service expenditure, it claimed. The unit was formed to gather relevant information and actionable feedback regarding the working of the various bodies under the jurisdiction of the Delhi Government and to do “trap cases” to check corruption, the FIR alleged.
