The ruling Awami League government announced it would take action against the patrons.

But no action has been taken yet though names of some former BNP-Jamaat-led ruling alliance's political leaders, lawmakers and ministers surfaced as patrons of JMB in the northern districts.

Some people in northern Rajshahi region have filed cases against some alleged patrons of JMB.

Aminul Haq, a former minister in the Khaleda Zia government, has been convicted by a court for patronising JMB and some other leaders of Zia-led Bangladesh Nationalist Party (BNP) have been accused in the cases.

Two of them, Maulana Obaidullah and Maulana Mansur Ali, were caught recently.

They were found to be hiding for over 13 years. They were masquerading as teachers in local madrassas while promoting JMB modules in Bangladesh in coordination with Pakistan-based Lashkar-e-Taiba.

Some Bangladeshi militants like Abdul Hannan have fled to India when pursued.

The former Jamaat-e-Islami Ameer (chief) of Habibganj district in northern Bangladesh, Maulana Saidur Rahman alias Mohammad Hanif alias Mohammad Kamal has been designated the new JMB chief.

The authorities have yet to arrest him 'as most of the time he is reportedly staying in Bashirhat and Murshidabad in India', New Age said, quoting sources in Rapid Action Battalion (RAB), an elite force aiding the police in anti-terror campaign.
