What if the police station doesn't arrest people?

Legal analysis: the police station has decided to issue a wanted order or an online wanted order if no one can be caught.

Legal basis: Article 153 of the Civil Procedure Law of People's Republic of China (PRC), in order to find out the case, when necessary, the relevant personnel may conduct an investigation under cover of their identities upon the decision of the person in charge of the public security organ. However, it is not allowed to induce others to commit crimes, and it is not allowed to use methods that may endanger public safety or cause great personal danger. For the criminal activities of paying drugs and other contraband or property, the public security organ may, according to the needs of investigating crimes, implement controlled delivery in accordance with regulations.
