After criminal detention, the police do not recommend looking for a lawyer.

Legal analysis: once relatives and friends are arrested or detained in a detention center, as family members or friends, they should first know the facts of the suspected crime from the public security organ or procuratorate handling the case at the first time. Secondly, he has the right to know the place of detention from the case-handling organ. According to the law, summons and detention shall not exceed 12 hours, and criminal suspects shall not be detained in disguised form by summons or detention. After detaining a person, the public security organ shall notify the detainee's family or his unit within 24 hours of the reason and place of detention, unless it hinders the investigation or cannot inform him.

Thirdly, if the detention notice has not been obtained after dozens of days of detention, this situation is usually that the prisoner is arrested in the field, and the detention notice of the case-handling department is sent to the police station where the suspect is registered, but the household registration police station cannot notify the prisoner's family because it cannot be contacted. Under normal circumstances, the public security organs will not ignore the procedure of notifying the family members, so the family members of prisoners need not be too suspicious. In this case, the prisoner's family can contact the local police station directly by telephone to find out whether there is a detention notice, so as to know the place and reason of the prisoner's detention.

Finally, if family members know where their relatives are detained or arrested, they can hire lawyers to meet at the detention center in time to safeguard the legitimate rights and interests of the parties.
