Following a tip-off, a team from Park Street police station raided a hotel in Marquis Street and nabbed a man who identified himself as Rabi Sharma, officials said.

To corroborate his identity, Sharma produced a photocopy of what he claimed was his Aadhaar card as well as a passport. A senior police official said, “Even after that, we felt something was amiss and questioned him further.”

After detailed interrogation, Sharma revealed that his original name was Selim Matabbar and that he was from Madarihat in Bangladesh, the police said. A local leader of the Bangladesh Nationalist Party (BNP) there, he fled from Bangladesh two years ago following a political dispute with the then ruling party Awami League and arrived in Kolkata.

After fabricating a fake identity and procuring false documents for the same, he managed to get an original passport, officials said. Since arriving in Kolkata, he had been working at a hotel on Marquis Street.

After his confession, Park Street police arrested the accused. He will be produced in court on Saturday.
