What's the difference between detention center and detention?

What's the difference between detention center and detention? In our country, detention is basically a state that decides to arrest and deprive citizens of their personal freedom after detention. It is not an independent compulsory measure. Places of detention include: prisons, detention centers, detention centers and detention rooms. 1. Is criminal detention and custody the same thing? Detention is different from detention. Criminal detention is not a penalty, but a temporary compulsory measure taken by public security organs. The object of detention is a person who is suspected of a major crime and may continue to commit crimes, escape, commit suicide or plead guilty. The detention period is 3 days, which can be extended by 1-4 days with the approval of the police chief. Criminal suspects who commit crimes on the run, commit crimes many times or commit crimes by gangs may be extended for 30 days. During the detention, if the suspect is released at any time and the evidence of the crime is found out, he should report to the procuratorate for approval of arrest at any time. If the procuratorate does not approve the arrest, it will be released immediately. If the procuratorate approves the arrest, it will continue to be detained. Second, what are the main differences between criminal detention and custody? In the Supreme People's Court's reply on detention and custody, the following distinction was made between detention and custody: "Detention is an emergency measure under legal conditions for criminals who need to be investigated before the arrest is approved, and only the public security organs can exercise the right of detention. Detention refers to the detention of criminals after the people's court decides to arrest or the people's procuratorate approves and executes the arrest; The organs that execute the arrest, that is, the people's courts, people's procuratorates and public security organs, can detain the criminals after they are arrested. " 3. What are the conditions of criminal detention? Article 6 1 of the Criminal Procedure Law adopts the enumeration method, stipulating that a flagrante delicto or a major suspect under any of the following circumstances shall be punished. The public security organ may detain in advance: 1 Those who are preparing to commit a crime, commit a crime or are found immediately after committing a crime. 2. The victim or the person who saw it with his own eyes found him guilty. 3. Found criminal evidence around or at the residence. 4. Attempted suicide, escape or escape after committing a crime. 5. It is possible to destroy, forge evidence or collude with others. 6. Don't tell your real name, address and unknown origin. 7. Suspected of committing crimes on the run, committing crimes many times, and committing crimes in partnership. Detention centers are called custody and detention in order. Generally speaking, prisoners in custody have been tried or convicted of some crimes. Detention is a detention measure for those involved in the case, which provides some preparation conditions for the review of subsequent cases. Detainees have a certain time limit, and those who exceed the time limit need to be released unless they apply to the relevant departments for further detention.
