At least 21 of the 41 murders committed in Chattogram over the past year are linked to criminal gangs operating through foreign phone numbers and encrypted messaging apps such as WhatsApp, Imo, and Telegram. These networks, reportedly run by masterminds based in India, Saudi Arabia, Oman, Dubai, and Qatar, issue orders for killings, extortion, and abductions remotely. Police admit they lack the technical capacity to trace these encrypted communications, leaving them unable to pinpoint suspects’ locations even when nearby. Intelligence reports identify at least 14 active groups, each backed by expatriate coordinators and hackers skilled in number cloning and fake location generation. Local law enforcement officials say their efforts are hampered by limited access to advanced surveillance tools and dependence on a single military intelligence agency for technical assistance. Experts warn that Chattogram’s underworld has undergone a ‘digital shift,’ urging immediate investment in cyber intelligence, international data-sharing agreements, and modern monitoring systems to prevent virtual criminal networks from becoming uncontrollable.
