What's the difference between criminal police arresting people and public security arresting people?

The difference between criminal police arresting people and public security arresting people is that criminal police arresting people is carried out under the condition of criminal facts, and the arrest is examined and approved by the procuratorate. It is a criminal case with serious consequences. In addition to the above similar arrests, arresting people at the police station is not arresting people, but investigating and summoning or handling them at the police station after going out to report to the police.

The people's procuratorate shall, within three days from the date of receipt of the case materials transferred for examination and prosecution, inform the victims and their legal representatives or their close relatives, the parties involved in incidental civil litigation and their legal representatives that they have the right to entrust agents ad litem. The people's court shall, within three days from the date of accepting a case of private prosecution, inform the private prosecutor and his legal representative, the parties to an incidental civil action and his legal representative that they have the right to entrust an agent ad litem.

Judges, prosecutors and investigators must collect all kinds of evidence that can prove the guilt or innocence of criminal suspects and defendants and the seriousness of the crime in accordance with legal procedures. It is strictly forbidden to extort confessions by torture and collect evidence by threats, enticements, deception or other illegal methods, and no one may be forced to prove his guilt. It is necessary to ensure that all citizens who are related to or know the case have the conditions to provide evidence objectively and fully, and they can be hired to assist in the investigation except in special circumstances.

Evidence materials such as physical evidence, documentary evidence, audio-visual materials and electronic data collected by administrative organs in the process of administrative law enforcement and case investigation can be used as evidence in criminal proceedings. Evidence involving state secrets, commercial secrets and personal privacy shall be kept confidential. Whoever forges, conceals or destroys evidence, and whoever the evidence belongs to, will be investigated by law.
