Police yesterday recovered 12 bombs and a huge cache of bomb-making materials from the militants' hideout “Chhayaneer” in Sitakunda where four militants were killed during a raid on Thursday.
The militants' den was sealed off at the end of an operation named “Assault-16”.
A bomb disposal unit along with forces from the Police Bureau of Investigation (PBI) entered the den around 11:45am yesterday and searched the three-room flat on the ground floor in Premtala area till 4:30pm.
As a large amount of explosives littered the rooms, the den was sealed off on Thursday night to avert any untoward explosion, said Deputy Inspector General (DIG) Shafiqur Rahman of Chittagong Range.
During the search, 12 bombs, five jars each containing 40 litres of Hydrogen Peroxide and 50 litres of acid were found in the front room of the flat, said the DIG.
“It will take several days to deactivate the bombs,”he added.

They both hailed from Baisari of Naikhyangchhari upazila in Bandarban.
Jasim had rented the houses at “Sadhan Kutir” and “Chhayaneer” providing fake NIDs to the owners, said police source.
“We are interrogating Jasim and his wife to find out the identities of the other militants killed during the operation,” said the OC.
