A former bank customer manager in Hong Kong was sentenced to four years in prison for accepting cryptocurrency bribes and assisting in the verification of forged financial documents. The case involved China Construction Bank (Asia), fintech company Vesttoo, and over $1.6 billion in fraudulent standby letter of credit documents.
Submit USDT verification documents
Lin Junxian, 32, formerly served as a client relationship manager at China Construction Bank Asia. He admitted to conspiring to accept bribes. The case revealed that, between April and June 2022, he received over $470,000 in Tether (USDT) as payment for verifying multiple forged standby letter of credit documents.
These documents, falsely claimed to be issued by China Construction Bank, include two forged collateral letters involving amounts exceeding $1.6 billion. Court records show that at the time, Lin Junxian worked in the retail banking division, serving individual customers, and had no authority to handle commercial credit arrangements or issue letters of credit.
The Vesttoo transaction is linked to the case.
The documents in question relate to transactions involving Vesttoo Limited. The company operates an insurance-linked investment platform, requiring investors to provide a standby letter of credit issued by a bank as collateral.
After Yu Po Holdings became an investor, the relevant parties arranged Lin Junxian to serve as the CCB liaison responsible for verifying the authenticity of documents. Subsequently, he provided false certification of the documents after receiving cryptocurrency.
After an internal investigation, China Construction Bank (Asia) discovered that the involved standby letter of credit and collateral documents were not issued by the bank or its affiliates, leading to the exposure of the case.
The court sentenced the individual and ordered the recovery of HK$3.7 million.
Hong Kong District Court Judge Lam Ka-hung sentenced Lin Junxian to four years in prison and ordered him to repay approximately HK$3.7 million, equivalent to the value of the bribes he received.
The judge noted that, even though the defendant was a first-time offender, a deterrent sentence was necessary because the case affected Hong Kong's banking and insurance industries and could damage Hong Kong's reputation as an international financial center.
In addition, Lin Junxian faced a charge of using forged documents, but the court filed this charge without further proceedings. The Independent Commission Against Corruption of Hong Kong stated that corruption syndicates are increasingly using cryptocurrencies to conceal illicit payments, and arrest warrants have already been issued for other individuals involved.
