The man was held from the immigration area in a joint drive of the Immigration Police and Department of Narcotics Control on Tuesday morning.
The department’s Deputy Director Md Jafarullah Kajal told bdnews24.com they had got a tip-off about the Peruvian national in the flight of Emirates Airlines from Dubai which touched down around 8:30am.
He added they were going to take legal steps and were working to find out the haul’s street value.
According to prices in Peru’s black market, it is worth around $8,100.
Recently a large haul of liquidated cocaine mixed with sunflower oil was seized from Chittagong port.
The consignment came from Peru’s neighbouring country, Bolivia.
