My bank card was frozen, and the bank said it was looking for a special criminal investigation line in Lanzhou, Gansu. How can I check the phone number?

1. The bank card has been frozen by the judicial authorities. Will the Public Security Bureau contact you? 1. Yes. Because bank cards are related to some legal and public security cases. If a criminal case is involved and the bank card is frozen by the judicial organ, the public security organ will contact the party concerned, and if the party concerned is a criminal suspect, compulsory measures may be taken. 2. Legal basis: Article 144 of the Criminal Procedure Law of People's Republic of China (PRC), people's procuratorates and public security organs may, according to the needs of investigating crimes, inquire about and freeze the deposits, remittances, bonds, stocks, fund shares and other properties of criminal suspects in accordance with regulations. The relevant units and individuals shall cooperate. If a criminal suspect's deposits, remittances, bonds, stocks, fund shares and other properties have been frozen, they may not be frozen again. Second, will the bank card be frozen after imprisonment? It depends. If the defendant needs to execute the effective judgment and involves money, but the defendant refuses to execute it, the court may freeze the defendant's bank card account according to the application of the party concerned. According to the law, the people's court has the right to seal up, freeze, transfer or change the price of the property of the person subjected to execution according to different circumstances. If the person subjected to execution fails to perform the obligations specified in the legal documents according to the notice of execution, the people's court has the right to inquire about the deposits, bonds, stocks, fund shares and other property of the person subjected to execution from the relevant units. The people's court has the right to seal up, freeze, transfer or change the property of the person subjected to execution according to different circumstances. The property inquired, sealed up, frozen, transferred or changed in price by the people's court shall not exceed the scope of obligations that the person subjected to execution shall perform. When the people's court decides to seal up, freeze, transfer or change the price of property, it shall make a ruling and issue a notice of assistance in execution, which the relevant units must handle.
