1. The Public Security Bureau needs to report to the court to freeze the bank accounts involved because of handling cases or judicial needs. 2. The court sends a letter to the bank, which responds and signs it. 3. The general freezing period is six months, which can be extended once according to the demand, usually three to six months. 4. If you are suspected of breaking the law, you can freeze the account permanently. Bank cards are generally unfrozen within six months after the statement is entered. The bank card was frozen by the public security court, which was suspected to be related to online gambling. After the investigation is completed, if there are no other problems, the account will be unfrozen in time. If it has nothing to do with online gambling, you can hire a lawyer to issue a legal opinion to the public security and procuratorate for help. Unfreeze the bank card as soon as possible.
