First, administrative detention. The police station has no right to make a detention decision, but the public security organ of the people's government at or above the county level can make a detention decision. According to the Public Security Administration Punishment Law, the public security administration punishment is decided by the public security organs of the people's governments at or above the county level; Among them, warning and fines below 500 yuan can be decided by the police station.

The public security organ shall announce the decision on administrative penalties for public security to the person being punished and deliver it to the person being punished on the spot; If it cannot be announced to the punished person on the spot, it shall be served to the punished person within two days. If it is decided to give administrative detention, it shall promptly notify the family members of the punished person.

Second, criminal detention. Article 83 of the Criminal Procedure Law stipulates that when a public security organ detains a person, it must produce a detention permit. After detention, the detained person shall be immediately sent to the detention center for custody, and shall not exceed twenty-four hours. Unless it is impossible to notify or the notification of suspected crimes endangering national security or terrorist activities may hinder the investigation, the family members of the detained person shall be notified within 24 hours after detention. After the circumstances that hinder the investigation disappear, the family members of the detained person shall be notified immediately.
