Calcutta Police Commissioner Soumen Mitra on Friday said that the organisation of fake Covid-19 vaccination camps by a man pretending to be an IAS officer is an act of a "distorted mind".

Debanjan Deb, a 28-year-old man who held several camps where around 2,000 people were suspected to have been inoculated, was arrested earlier this week.

"What Debanjan has done is very inhuman. It can only be done by one with mental distortion," Mitra told reporters.

After inaugurating a vaccination camp in the city, the police commissioner said that the matter is being investigated.

The police arrested Deb on Wednesday for allegedly posing as an IAS officer and organising a Covid-19 vaccination camp in Kasba area, where actor and Trinamul Congress MP Mimi Chakraborty had also got her jab.

Chakraborty, who was invited to attend the camp, said she became suspicious about the vaccination process as she did not receive the customary SMS that is sent to people after they are administered a dose, and informed the police.

During a search in his office, police seized several vials of an antibiotic injection used for a number of bacterial infections, and other items which were sent for tests.

It was also found that fake labels of Covaxin were pasted on the vials of Amikacin injections.

On what could be the purpose of Deb in holding such free camps, a senior Calcutta Police official said it is yet to be known but he might have political connections that helped him in organising those camps.

The Calcutta Municipal Corporation has started spotting people who have taken Covid vaccines from his camps.

Deb used to introduce himself as a joint commissioner of the CMC and travel in a large car with the logo of the state government.

The police found "forged seals and papers" of the CMC from Deb's office.

It was also revealed during the investigation that the arrested man opened several bank accounts in the names of senior CMC officials using fake documents.
