A special team of Maharashtra Police will interrogate 11 Muslim men in Agartala who were detained near the Bangladesh border, officials said on Sunday.
Director General of Police GM Srivastav said that it was yet to be finalised when the team would arrive in Tripura from Maharshtra.
The 11 men were detained on Thursday from a mosque at Sonarai, a village near the border with Bangladesh, for their suspicious activities.
They had entered Kamalpur sub-division of Dhalai district of Tripura on June 26.
Srivastav said Tripura Police had sent photographs and residential addresses of the men to Mahasrashtra Police to ascertain their antecedents.
Though no evidence of criminal activities has been established so far against the men, Maharashtra Police have requested their Tripura counterparts to keep them under strict surveillance because their involvement with some religious militant groups could not be ruled out.
Srivastav said the men had during their interrogation revealed that a 12th member of the group, Faizul Ansari, was reported missing three days before the Mumbai blasts and he was a wanted man on police records.
He said three of the men were highly educated, and one of them was a software engineer who studied in US and also worked for Microsoft.
"When such people stayed in a mosque just near the border close to Sylhet, where Muslim militants have their training camps, it can give rise to suspicion," Srivastav said. "We have to remain alert because many youths are working in the garb of religious outfits."
