Rapid Action Battalion (RAB) has destroyed four poppy fields in Ruma upazila of Bandarban.
It came after a raid in the upazila's Keokradong between 7am and 12pm on Friday, said RAB 7 Chief Moshiur Rahman.
No arrests were made in the course of the raid.
The RAB official said poppies were being cultivated across seven acres of land deep inside the forest in Keokradong. The owners of the farm aimed to export poppies abroad illegally.
RAB also recovered around sixty kilograms of poppy nectar from the four fields. Later, the elite police unit torched the fields and the nectar, said Moshiur.
Law enforcers have launched a search for the owner of the farm and a case will be soon filed in this regard, he added.
