The Rapid Action Battalion (RAB) on Tuesday detained three suspected scammers of foreign nationality from Dhanmondi and Bashundhara residential areas in Dhaka.
RAB-4 Commanding Officer Md Mozammel Haque made the disclosure at a press briefing held at RAB media centre on Wednesday.
The detained suspects are Cameroon nationals Tchikamen Rodrigue, 31, Dongmeza N Guengni, 32, and Alexandre Mafeja, 48. Mafeja is the leader of the scammer group.
During the primary interrogation, the detainees confessed their involvement with fraudulent activities since 2017, said RAB sources.
Mafeja, along with his two associates, came to Bangladesh from Cameroon using a travel visa, RAB sources said, adding that the visas had expired and they were living in Bangladesh illegally.
Elite Businessmen from Dhanmondi, Gulshan, Banani, Baridhara areas were their primary targets.
They used to offer alluring business proposals of making easy profit -- turning Taka into US dollars using a 'box'. Several businessmen had been victimized by the scammers, RAB sources said.
“Though only 3 victims complained to us regarding the scam, there are many other victims who are reluctant to report the matter to the authorities,” RAB-4 Commanding Officer Md Mozammel Haque said.
The 3 victims claimed to have lost around Tk3 lakh.
