Kolkata, Nov 25 (IANS): Three days after the arrest of two suspected members of Bangladesh-based Islamist group Ansarullah Bangla Team (ABT), a Bangladeshi who helped them cross over to India illegally was arrested here on Friday, a senior officer said.

"Mohammad Sahadat Hossain, a Bangladeshi tout, was arrested from near the Sealdah railway station. He helped the two ABT members cross over and also helped them get jobs in Hyderabad," Deputy Commissioner of Kolkata Police (STF) Muralidhar Sharma told IANS.

The officer said Hossain himself had entered India illegally as he failed to produce any legal documents to this effect after his arrest.

The Special Task Force also released photographs of two more suspected ABT members on Friday.

"We have released the pictures of two ABT members -- Shopon Biswas alias Sajol Ahamed Alias Tamim (23) and Nayan Gazi alias Zafor alias Ariful Gazi, aged between 28 and 30. Both are residents of Bangladesh," Sharma said.

"They were in Kolkata in October but we are now unaware about their current location. So, we have released their pictures so that anyone aware of their whereabouts can report to us," he added.

The STF arrested the two members of ABT, a front for Al Qaeda in the Indian subcontinent, and a local arms dealer on November 21 from a city railway station and seized a cache of arms, gadgets and incriminating documents from them.

All three have been remanded to police custody till December 5.
