A team of Rapid Action Battalion (RAB)-7 conducted a drive in Keokradong area of Bandarban's Ruma upazila and destroyed four poppy fields there on Friday morning.
They have seized around 60 kilogrammes of poppy juice (used to make opium) from the spot.
Mashiur Rahman of RAB-7, who led the operation, said, "Acting on a tip-off, we led a drive in the deep forest near Keokradong where we found the poppy fields. The poppies were cultivated in order to be smuggled abroad."
"We are investigating who owns these fields," he said, adding that legal action will be taken against them.
