CBI officers interrogated some of these official account holders who confessed that they were forced to open the accounts by SILL. They were also forced to submit entire supporting documents like passbooks, checkbooks and even debit cards to the SIIL. Sources said that the official account holders had no authority to operate those accounts.

The second interesting factor in the scam, as revealed by the investigating officers, is how a section of middlemen, who are linked to SIIL, used the process to earn huge sums of money in two ways.

The first proceeds were a commission from the recipients or ultimate beneficiaries or recipients of the proceeds in the alleged scam. At the same time, after receiving the appointment letters, this class of agents also collected commission from those candidates.

The scam allegedly occurred in several civic bodies between 2014 and 2018.
