Guwahati, Oct 16 (TIWN / IANS) Thirty-one Bangladeshi nationals were detained at the railway station here on Monday, a police official said.

"The group came to Guwahati from Bengaluru onboard the Guwahati-Bangalore Express. They were waiting to board the Kanchanjungha express to go to Agartala," Superintendent of Railway Police Hemanta Kumar Das told the media here.

"During questioning, they admitted that they were from Bangladesh and had entered India without any valid documents some four years ago and were working in Bengaluru as manual labourers.
