The arrests were made during an overnight raid at Dhaka’s Hazaribagh.
In another related development, the Dhaka Metropolitan Police said on Wednesday morning that they had arrested 14 activists of the Jamaat-e-Islami’s student wing from a ground-floor apartment in the same area.
Police have been conducting search operations at different parts of the capital almost every night following the Gulshan and Sholakia terror attacks last month.
During one of these routine searches, a gunfight erupted early on Jul 26 between police and suspected militants holed up in an apartment at Kalyanpur.
The SWAT team stormed the apartment later and nine suspected militants were gunned down, said police.
The Bangladesh government had banned six Islamist outfits for militant and subversive activities. They are Jama’atul Mujahideen Bangladesh (JBM), Jagrata Muslim Janata Bangladesh (JMJB), Harkat-ul Jihad al-Islami Bangladesh (HuJI,B), Shahadat-e al-Hikma, Hizb-ut Tahrir and Ansarullah Bangla Team (ABT).
Intelligence agencies suspect ABT has links with al-Qaeda.
RAB officials said they have seized a huge amount of jihadi literatures and training manuals found in possession of the activists of the new group, al-Ansar (HuJI).
RAB- 2 chief Md Mahiuddin told bdnews24.com the overnight raid ended at 5 in the morning.
He said they were held from an apartment in a building at Hazaribagh, which they had rented.
