Dhaka: Members of Counter Terrorism and Transnational Crime (CTTC) in a drive arrested four suspected arms suppliers of Gulshan café attack from Darus Salam area in the city on Wednesday night.

Tipped off, a CTTC team conducted a drive in the area at 9:00pm on Wednesday and arrested them, said Deputy Commissioner (Media) Masudur Rahman of Dhaka Metropolitan Police (DMP). 

The arrestees are Abu Taher, 37, Mizanur Rahman, 34, M Selim Miah, 45, and Towfiqul Islam alias Dr Towfiq. 

All of them are the members of the banned militant outfit Jama'atul Mujahideen Bangladesh (JMB), he said.

The CTTC team also recovered the prime elements of handmade grenade, 787 detonators and a nine mm pistol from their possessions.

During primary interrogation, the four JMB men said they are active members of JMB and they used to smuggle arms and explosives through Indian border in Shibganj upazila of Chapainawabganj district, he said. 

Mizanur Rahman alias Boro Mizan, also the chief of Chapainawabganj unit of JMB, and Mizanur Rahman alias Choto Mizan collected the arms and explosives from several places, said Masudur quoting the arrestees. 

Choto Mizan collected arms, including pistols and detonators-making raw materials, from the arrestees from Chapainawabganj border. Later, he supplied those to Gulshan attack mastermind Tamim Chowdhury and Marzan. 

Police suspected that the four JMB men gathered in the capital with the arms and explosives to carry out subversive activities, Masudur said.
