Three persons have been arrested for allegedly forging the Calcutta municipal commissioner’s stamp and signature to purportedly recruit a group C employee in the government office.

When the candidate who was fraudulently appointed went to join work, CMC officials told him that the appointment letter he was carrying was fake, police said.

Based on a complaint lodged by the overseer of the conservancy department, officers of New Market police station initiated a case against a man named Rajib Mallick.

Mallick had allegedly taken money from the candidate and provided him with a purported appointment letter carrying the CMC commissioner’s signature.

Mallick, a resident of central Calcutta’s Eden Hospital Road, was arrested on June 27. Based on his statement, cops picked up his accomplices Joydeb Sarkar and Siddhartha Saha. Investigators seized a fake rubber stamp of a senior CMC official and six fake letter-heads of the corporation from them.

Till Wednesday, the police said they had not found any connection with the Debanjan Deb case.

The modus operandi through which Mallick had allegedly cheated the candidate bore a resemblance with that of Deb, who not just feigned the identity of an IAS officer posted as a joint commissioner in the CMC, but also gave purported appointment letters to several people using forged government documents, seals and stamps.
