Korean news outlet JTBC reported on Feb. 2 that the Seoul Southern District Court has issued an arrest warrant against Kang Jong-hyun.

Jong-hyun was arrested alongside two Bithumb executives for fraud, stock manipulation, and embezzlement of corporate funds worth 60 billion won – approximately $50 million.

Further investigations revealed that Jong-hyun is the elder brother of Kang Ji-yeon, the head of Inbiogen, an affiliate with about 34.2% stake in Bithumb.

The duo allegedly conspired to manipulate the stock prices of Inbiogen and embezzled corporate funds to the tune of ₩‎60 billion.

Jong-hyun denied the embezzlement allegations, stating that he has no relation to the company as he no longer has a stake in them.

Kang Ji-yeon added that the claims against his brother were “unconfirmed.” However, he would cooperate with the authorities in the investigation.

Meanwhile, South Korea’s National Tax Service (NTS) said it was probing the tax affairs of Jong-hyun and Kang Ji-yeon to uncover possible tax evasion and money laundering.
