India handed over 175 Bangladeshi nationals rescued around eight months ago from the sea near the Andaman Islands.
Most of the returnees hail from Cox's Bazar and Bandarban.
Tareque Mohammad Ariful Islam, counselor of Bangladesh mission at Kolkata, officials of Bangladesh Rifles, police, and Bangladesh Red Crescent Society formally received them at Benapole.
Indian coastguards went to their rescue when they were left marooned in the sea by the Thai navy last December.
The navy caught them on their way to Malaysia and they took off the engines from the trawlers.
The Andaman Islands authorities sheltered them for the last several months.
Tareque said that after having permission from Indian government, they were brought to Kolkata from Port Blair, the capital of Andaman Islands, last Thursday. They reached Kolkata on Sunday.
