Syndicate Accused of Laundering Money Abroad
During preliminary interrogation, the detainees reportedly confessed to being active members of an organised syndicate involved in online gambling, cyber fraud, illegal electronic transactions and money laundering.
Investigators said the group collected mobile financial service agent SIM cards registered under different names from various parts of the country and used GSM Gateway devices to keep hundreds of SIMs active at the same time. The SIM cards were allegedly used to process gambling transactions, fraud proceeds and other illegal financial activities.
Police said the syndicate also operated its own online gambling portals and laundered crores of taka abroad, particularly to China. A case has been filed against the arrested persons under the Cyber Security Act with Ramna Police Station.
