In total, four separate violations were recorded, involving 17 foreign nationals, including three Nigerians, five Pakistanis, seven South Koreans, and two Chinese citizens. Upon interrogation, the seven South Koreans admitted they had entered Vietnam to operate an online fraud scheme under the direction of two Chinese organizers. The suspects claimed to be temporarily residing in a different urban area in Tay Mo ward, Hanoi. When police followed up on this lead, they uncovered seven passports matching the suspects' identities. Simultaneously, four other inspection teams combed various areas in Hanoi, including Kim Lien ward, Hong Ha ward, and the rural communes of My Duc and Quang Bi.
