Can you ask someone for help to ask the public security bureau about the suspect's case?

Yes, but the fundamental way is to entrust a lawyer to defend. Only lawyers can meet the suspect before the judgment takes effect. Family members may consider entrusting a lawyer to the detention center to meet the criminal suspect, and carefully understand the specific process of the whole case and his confession to the public security organ. After the meeting, the lawyer will judge the circumstances of the crime and provide legal help and apply for bail pending trial in time; If the case is transferred to the procuratorate or the court, the defense lawyer can go to the procuratorate or the court to read the papers, collect the confessions, documentary evidence, physical evidence and other relevant evidence of the criminal suspect and other accomplices accused by the investigation organ, and make a good defense plan after in-depth study, so as to ensure that the defendant is innocent, mitigated, exempted from punishment or declared suspended during the trial, and safeguard the best interests of the defendant. Specific criminal defense procedures can be found on the legal website "Rules for Lawyer Zeng Yongqian to Handle Criminal Cases".

Under normal circumstances, you can't arrest people without a search warrant.
