South Korean prosecutors arrest two police officers in a crypto laundering probe linked to voice phishing and illegal exchanges.
South Korean authorities are examining a major corruption case tied to illegal crypto exchanges and voice phishing schemes.
The investigation shows how criminal groups used digital assets to disguise funds, while two police officers accepted money and goods to protect criminals.
South Korean Police Officers Arrested For Crypto Bribes
Two police officers, identified as a superintendent and a senior officer, were arrested on November 27.
Prosecutors said both officers accepted money from operators who ran illegal crypto exchanges. These exchanges helped move proceeds from a large voice phishing network that processed about $186 million.

The first, referred simply to as “Officer G” accepted cash and luxury goods worth about $7,500. The other, “Chief F” received around $59,000 between July 2022 and February of last year.
Prosecutors said the officers offered investigative details and support in exchange for money. They also linked the suspects to lawyers, asked for account unfreezing and connected them with other law enforcement staff.
Both officers have been dismissed from their jobs.
How The Illegal Crypto Network Operated
Prosecutors said an unknown operator worked with one of their clients, “CEO B” to manage a team that ran illegal cash-for-crypto exchanges.
These operations ran from January to October of last year, and the group placed these exchanges in busy areas such as Yeoksam-dong and disguised them as gift certificate shops.
They also placed signs that warned customers to beware of voice phishing to appear legitimate.
The group converted profits from voice phishing into USDT and Officials found that about $1.1 million in assets were frozen during the investigation. This included $600,000 held in USDT, and prosecutors said the group spent or hid another $8.4 million.
Komodo Platform CTO, Kadan Stadelmann, commented that sharing wallet details can push suspects toward mixers and privacy tools.
He added that this weakens anti-money laundering work. He also stressed that communities must expect their police to follow the law.

Rising Crypto Crime Cases Across South Korea
The recent arrests follow an increase in crypto-linked crimes across the country. Authorities have seen several cases where criminals used digital assets to move or hide funds.
Earlier this year, a South Korean national was arrested at Suvarnabhumi Airport on August 23. He was linked to a group that laundered crypto into gold worth more than $44 million.
The Criminal Court charged him with impersonation, money laundering and inputting fraudulent data into a computer system.
Another case surfaced on November 13 of last year, when authorities arrested 215 people in the country’s largest crypto investment scam. The group stole about $228 million from more than 15,000 victims and police said the ring marketed 28 tokens and promised large profits.
The leader, known as Mr A, fled to Australia before being arrested. Yonhap reported that police seized 22 Bitcoins from his account and filed to seize another $34 million.
Lawmakers say these cases show a rise in the misuse of digital assets. Democratic Party legislator Jin Sung-joon said that cryptocurrencies are appearing more often in illegal foreign exchange activities and money laundering.
Overall, the bribery case shows how criminal groups adapt quickly. It also shows how law enforcement must stay alert as these methods grow more in complexity.
