I want to ask a lawyer, suspected of obstructing official detention. The police said it would take 30 days, so can he be released after 30 days?

First of all, you should ask whether the personal control exercised by the public security organs is criminal detention or administrative detention. If it is administrative detention, the public security organ shall issue a written decision on administrative punishment and punish you accordingly. Moreover, the longest period of administrative detention is 15 days, and the longest period of combined execution of multiple punishments for violating public security is 20 days, so it cannot be said that there is no such thing as 30 days.

If it is not the above administrative detention, unfortunately, I tell you that you may be suspected of a criminal offence. If you are under personal control on the grounds of suspected obstruction of official duties, you should ask clearly whether to summon, detain or arrest me at this stage. In case of summons or compulsory summons, a summons certificate and a compulsory summons certificate shall be issued, and the longest summons period shall not exceed 12 hours. If it belongs to criminal detention, the public security organ at or above the county level shall issue a certificate of criminal detention. If not, you can refuse to cooperate. And the public security organ must notify your family or unit within 24 hours. If the other party issues a residence permit, then you have to cooperate. During the 24-hour detention, the public security organ should question you. After the first interrogation, you can also hire a lawyer to provide legal services for you. The longest period of criminal detention is three days, during which the public security organ must decide whether to report to the procuratorate for arrest. According to the law, the longest period can be extended to four days. If it is multiple times, escape or gang, it can be extended for 30 days.

If it is an arrest, there must be a decision of the procuratorate to approve the arrest. I guess you haven't come this far. Obviously, the police have completely scared you now, and your panic at this time is exactly what they want. You don't have to be afraid to operate according to law. If you are from Jiangsu and Zhejiang, you can contact me.
