In the investigation stage of criminal proceedings: the public security organs can criminally detain current offenders or major suspects. Detainees must be questioned within 24 hours of detention. After the criminal suspect is interrogated for the first time by the investigative agency or from the date when compulsory measures are taken, a criminal suspect may hire a lawyer to provide him with legal advice, appeals and accusations. The entrusted lawyer has the right to learn from the investigation agency about the charges against the criminal suspect, meet with the criminal suspect in custody, and learn from the criminal suspect about the relevant situation. If the public security organ deems it necessary to arrest a detained person, it shall submit the matter to the People's Procuratorate for review and approval within three days of detention. Under special circumstances, the approval time may be extended by one to four days. For major suspects who commit crimes on the fly, commit crimes multiple times, or conspire to commit crimes, the time for review and approval can be extended to 30 days. The People's Procuratorate shall make a decision to approve or disapprove the arrest within seven days after receiving the approval letter from the public security organ. If the People's Procuratorate does not approve the arrest, the public security organ shall release the person immediately upon receiving the notice and promptly notify the People's Procuratorate for execution. For those who need to continue investigation and meet the conditions for release on bail pending trial or residential surveillance, they will be released on bail pending trial or placed under residential surveillance in accordance with the law.
