Fourteen Bangladeshis, including five children, returned home through the Benapole check-post on Thursday night after languishing in an Indian jail for a year and a half.
Tarikul Islam, officer-in-charge of Benapole immigration police, said Petrapole immigration police handed them over to their Bangladeshi counterparts around 9pm.
The victims had entered India two years ago without valid documents through a Jessore border point in search of jobs.
Indian police arrested them from Kolkata.
Later, an Indian court sentenced them to one and a half years in jail.
The process to bring them back started following a joint intervention by the home ministries of the two countries.
Motiar Rahman, a sub-inspector at Benapole port police station, said police handed the returnees over to their families.
