According to the provisions of the Criminal Procedure Law, public security organs are the main investigation organs of criminal cases. When investigating criminal cases, public security organs can arrest criminal suspects under certain conditions, and arrest is the most severe criminal compulsory measure.

When the public security organs investigate credit card fraud cases, the procedures for the public security organs to arrest criminal suspects are as follows:

1. Review whether the suspect meets the conditions for arrest, such as possible new credit card fraud and possible destruction of criminal evidence.

2. If the conditions for arrest are met, the public security organ may detain them first, then apply to the procuratorial organ for arrest, submit an application to the procuratorial organ and transfer the evidence materials to the procuratorial organ.

3. After the procuratorial organ approves the arrest, the public security organ may arrest the suspect with an arrest warrant and transfer the suspect to the detention center for custody.

To arrest a criminal suspect who commits the crime of credit card fraud, it is necessary to examine whether he meets the conditions for arrest, and submit an arrest to the procuratorial organ, and the arrest can only be carried out after the approval of the procuratorial organ.

Legal basis:

Article 87 of the Criminal Procedure Law of People's Republic of China (PRC) stipulates that when a public security organ requests the arrest of a criminal suspect, it shall write a letter of approval for the arrest and transfer it to the people's procuratorate at the same level for examination and approval together with the case file and evidence. When necessary, the people's procuratorate may send people to participate in the discussion of major cases by public security organs.
