Immigration officers in Tangerang recently busted a scam ring after a routine visa extension flagged a suspicious return flight ticket, leading officers straight to a rented apartment packed with more than 20 phones and computers.

The syndicate had been operating out of an apartment in Klapa Dua for over a month, targeting gamblers in Vietnam. Two Chinese nationals managed the back-end operations and finances, while several Vietnamese nationals used local bank accounts to collect the betting funds. Daily turnovers ranged from tens to hundreds of millions of Vietnamese dong, moving massive sums of money.

Those arrested confessed they were hired by a Chinese boss known only as "B," who gave orders exclusively via Telegram and remains at large. Immigration officials later intercepted two Vietnamese suspects trying to flee at the airport, bringing the total number of people detained to seven. Local authorities are continuing to trace the mastermind and follow the money trail as the investigation unfolds.
