Obaidullah built the safe-shelter under the cover of a kindergarten named 'Noor Shah Islami Kindergarten' in Habiganj's Shayestaganj upazila (sub-district).

Bangladesh intelligence sources, however, say that Obaidullah has not revealed all the details about his operations in Bangladesh since his arrival in 1995.

In his statement, Obaidullah said several other militants in Bangladesh visited his safe-home, including Moulana Mohiuddin, who he claims to have known from the Deoband madrassa, and Harkat-ul Jihad's Bangladesh leader Mufti Abdur Rouf.

Deoband in India's Uttar Pradesh state is where Darul Uloom, a world renowned centre for Islamic theology has been functioning. It denies having imparted any training in militancy to the thousands of students from across the world who study there.

In 2005, Obaidullah met ARCF's new chief Amir Reza in Dhaka's Goran area. There, Amir asked Obaidullah to buy a permanent safe house and provide Jihadi training to Bangladeshi recruits.

Obaidullah claims they insisted on giving him the responsibility for the camp despite his reluctance.

Bangladesh authorities have in the recent weeks nabbed several militants who have yielded valuable information about the nexus among the militant groups in Pakistan, India and Bangladesh and the role of international mafia don, Dawood Ibrahim.
