Earlier, Debanjan Deb who was impersonating as an IAS officer was arrested by Kolkata Police for conducting fake vaccination drive.
Officials informed during the day about arrest of another associate of Deb, who was apprehended for allegedly masterminding fake vaccination camps in the metropolis.
Deb even conducted a raid as an "IAS officer" and the report of it with his photo was published in a newspaper, the official said.
Banerjee said that the Trinamool Congress government has no role in organising the fake Covid vaccination drive and rejected the BJP's demand for a CBI probe on the matter.
Deb, who had impersonated as a joint commissioner of the Kolkata Municipal Corporation, also insisted that he had set up two fake camps in the city, and not multiple ones.
Deb, who lied to his family about becoming an IAS officer, might have used that money to organise fake Covid-19 vaccination camps, pay salary to his employees and rent for the office.
The incident triggered a political storm after purported photographs and videos of the arrested person along with several TMC leaders and ministers at various programmes came in public domain.
