Agartala: The interrogation of 24 Bangladeshi youths, who were arrested at Agartala railway station here on Thursday, has revealed a Kashmiri connection.

"A Kashmiri connection has been established so far. However, no terror link was found," a senior officer of Tripura police told The Telegraph on Saturday.

The officer said officials of the National Investigation Agency (NIA) interrogated the arrested Bangladeshi youths, aged between 20 and 30 years, for the second day on Saturday ti find out if they were linked to any international terror group.

The two-member NIA team, led by Vivekananda Das, arrived here on Friday to interrogate the 24 youths, who were arrested from Agartala Railway Station.

They were in possession of fake Aadhaar cards, outdated passports and had no valid documents of their stay in India.

Sources said interrogation had revealed that the boys illegally crossed the Indo-Bangla international border near Petrapole-Benapole in Bengal. They claimed to be students of a couple of madrasas in Deoband area of Uttar Pradesh, the police officer said.

However, NIA sleuths have reportedly tracked telephone calls made to them from Jammu and Kashmir.

"They were dressed in long robes and sported beards like the usual madrasa students. They also produced identity cards issued by some madrasas. They owned sophisticated and expensive mobile phones. It was found that calls were made to them from Kashmir," the official said.

No specific evidence of terror link with the arrested youths has been established so far. Interrogation is still in progress, he added.

"They are still interrogated at a secret location. Grilling will continue," official sources said.
