Article 61 Public security organs may initially detain an active criminal or a major suspect under any of the following conditions:

(1) if he is preparing to commit a crime, is in the process of committing a crime or is discovered immediately after committing a crime;

(2) if he is identified as having committed a crime by a victim or an eyewitness;

(3) if criminal evidence is found on his body or at his residence;

(4) if he attempts to commit suicide or escape after committing a crime, or he is a fugitive;

(5) if there is likelihood of his destroying or falsifying evidence or tallying confessions;

(6) if he does not tell his true name and address and his identity is unknown; and

(7) if he is strongly suspected of committing crimes from one place to another, repeatedly, or in a gang.

Article 62 When a public security organ is to detain or arrest a person in another place, it shall inform the public security organ in the place where the person to be detained or arrested stays, and the public security organ there shall cooperate in the action.

Article 63 The persons listed below may be seized outright by any citizen and delivered to a public security organ, a People's Procuratorate or a People's Court for handling:

(1) any person who is committing a crime or is discovered immediately after committing a crime;

(2) any person who is wanted for arrest;

(3) any person who has escaped from prison; and

(4) any person who is being pursued for arrest.

Article 64 When detaining a person, a public security organ must produce a detention warrant.

Within 24 hours after a person has been detained, his family or the unit to which he belongs shall be notified of the reasons for detention and the place of custody, except in circumstances where such notification would hinder the investigation or there is no way of notifying them.

Article 65 A public security organ shall interrogate a detainee within 24 hours after detention. If it is found that the person should not have been detained, he must be immediately released and issued a release certificate. If the public security organ finds it necessary to arrest a detainee when sufficient evidence is still lacking, it may allow the detainee to obtain a guarantor pending trial or place him under residential surveillance.

Article 66 When a public security organ wishes to arrest a criminal suspect, it shall submit a written request for approval of arrest together with the case file and evidence to the People's Procuratorate at the same level for examination and approval. When necessary, the People's Procuratorate may send procurators to participate in the public security organ's discussion of a major case.

Article 67 The chief procurator shall make the decision on a People's Procuratorate's examination and approval of the arrest of a criminal suspect. Major cases shall be submitted to the procuratorial committee for discussion and decision.

Article 68 After a People's Procuratorate has examined a case with respect to which a public security organ has submitted a request for approval of arrest, it shall decide according to the circumstances of the case either to approve the arrest or disapprove the arrest. If it decides to approve the arrest, the public security organ shall execute it immediately and inform the People's Procuratorate of the result without delay. If the People's Procuratorate disapproves the arrest, it shall give its reasons therefor; and if it deems a supplementary investigation necessary, it shall at the same time notify the public security organ of the need.

Article 69 If the public security organ deems it necessary to arrest a detainee, it shall, within three days after the detention, submit a request to the People's Procuratorate for examination and approval. Under special circumstances, the time limit for submitting a request for examination and approval may be extended by one to four days.

As to the arrest of a major suspect involved in crimes committed from one place to another, repeatedly, or in a gang, the time limit for submitting a request for examination and approval may be extended to 30 days.

The People's Procuratorate shall decide either to approve or disapprove the arrest within seven days from the date of receiving the written request for approval of arrest submitted by a public security organ. If the People's Procuratorate disapproves the arrest, the public security organ shall, upon receiving notification, immediately release the detainee and inform the People's Procuratorate of the result without delay. If further investigation is necessary, and if the released person meets the conditions for obtaining a guarantor pending trial or for residential surveillance, he shall be allowed to obtain a guarantor pending trial or subjected to residential surveillance according to law.

Article 70 If the public security organ considers the People's Procuratorate's decision to disapprove an arrest to be incorrect, it may request a reconsideration but must immediately release the detainee. If the public security organ's opinion is not accepted, it may request a review by the People's Procuratorate at the next higher level. The People's Procuratorate at the higher level shall immediately review the matter, decide whether or not to make a change and notify the People's Procuratorate at the lower level and the public security organ to implement its decision.

Article 71 When making an arrest, a public security organ must produce an arrest warrant.

Within 24 hours after an arrest, the family of the arrested person or the unit to which he belongs shall be notified of the reasons for arrest and the place of custody, except in circumstances where such notification would hinder the investigation or there is no way of notifying them.

Article 72 Interrogation must be conducted within 24 hours after the arrest, by a People's Court or People's Procuratorate with respect to a person it has decided to arrest, and by a public security organ with respect to a person it has arrested with the approval of the People's Procuratorate. If it is found that the person should not have been arrested, he must be immediately released and issued a release certificate.

Article 73 If a People's Court, a People's Procuratorate or a public security organ finds that the compulsory measures adopted against a criminal suspect or defendant are inappropriate, such measures shall be cancelled or modified without delay. If a public security organ releases a person arrested or substitute the measure of arrest with a different measure , it shall notify the People's Procuratorate that approved the arrest.
