A team of Bangalore police will arrive here on Wednesday to interrogate the Bangladeshi nationals who were arrested at Guwahati railway station on Monday.

Altogether 31 Bangladeshis, including 13 minors, who had illegally entered India, were arrested by the GRP after they arrived here from Bangalore by train on Sunday morning.

They spent the night on the platform and were to catch the Tripura-bound Kanchanjunga Express on Monday morning when they were apprehended. From Tripura, they were planning to enter Bangladesh.

They worked as daily wage earners in factories in Bangalore.

“The team of Bangalore police will question them how they reached Bangalore and whether they knew about other illegal Bangladeshi nationals staying there,” a source said.

He added that the Bangladeshi nationals were produced in the court of chief judicial magistrate, Kamrup (metro) here on Tuesday evening.

Four of them were remanded in GRP custody for four days while others were sent to judicial custody.

Those remanded in GRP custody are Md Suleman Sorrower, 39, Md Jamal, 27, Md Babu, 19 and Md Hassan Biswas, 18.

“Suleman possesses a voter ID card, a PAN card and an Aadhaar card,” the source said.

Suleman said he had entered India in 1996 and visited New Delhi with his parents who later returned to Bangladesh nearly eight years ago.

He went to Bangalore three years ago and worked in a plastic factory.

The others had illegally entered India two to three years ago. They said they hailed from Bagerhat district, Khulna division, Bangladesh.
