Criminal detention is a compulsory measure, not a penalty. Criminal detention is not a penalty, but a compulsory measure taken by public security organs against criminal suspects. Administrative detention is a kind of public security punishment. The object of punishment is a person who seriously violates public security management regulations, but does not constitute a crime. Detainees can be defendants, plaintiffs or others.
The longest period of criminal detention is 14 days. Major suspects who commit crimes on the run, commit crimes many times or commit crimes by gangs can be detained for up to 37 days. Generally speaking, the state organs confirm the possibility that someone has committed a certain crime, which means that they have exact evidence, so they also set a time limit to improve the effectiveness of the organs.
