In another drive on the same day, members of the elite force nabbed Shibir cadre Md Ramzan alias 'Bhagina' Ramzan, with one AK-47 assault rifle in Fatikchhari of the district.

Sources said a Rab team nabbed Ahmudya and his 10 accomplices when they were coming out of Aeochia Union Parishad (UP) office at Deodighirpar under Satkania upazila after Juma prayers. Ahmudya is the incumbent chairman of the union parishad.

They were going to a workers' rally of Satkania BNP in South Dhemsha.

A former cadre of Jamaat- e-Islami, Ahmudya was wanted in over 15 criminal cases. He was also reportedly evading 17-year rigorous imprisonment (RI) awarded in an arms case before he joined the ruling BNP in July this year.

Eight of the 10 arrested accomplices of Ahmudya have been identified as Mohiuddin, Kala Salim, Rashed, Nizam Mohammad Shafi, Abbas Uddin, Kamal and Minhaz. Identity of the other two could not be known.

Ahmudya joined Bangladesh Nationalist Party (BNP), with around 1,000 of his fellow Jamaat-Shibir leaders and activists on July 15. Joint Secretary General of the ruling BNP Goyeshwar Chandra Roy was the chief guest at that joining ceremony, while BNP Chittagong (South) district President Ahmad Khalil Khan, BNP Chittagong (North) district General Secretary Shahjahan Siraj and the party's Chittagong city unit Joint-secretary Abu Sufian were special guests. Satkania upazila BNP President AZM Moinul Haq Chowdhury presided.

Meanwhile, in another drive, Rab members arrested notorious Shibir cadre Md Ramzan alias Bhagina Ramzan with AK-47 assault gun from Narayanhat under Fatikchhari upazila at around 3.30pm.

Ramzan is the second-in-command of Jamaat-Shibir backed Nasir Bahini, a criminal gang based in Fatikchhari.

Ahmudya and his two accomplices were killed in a shootout with Rab at about 9:00 last night, sources said. Rab said Ahmudya did not die, but was critically injured in crossfire.
