You can call the detention center and ask if there is such a person.

Legal analysis: Call the detention center, and the detention center won't tell you. The situation of the detainees in the detention center is the secret of judicial work and cannot be disclosed casually. Moreover, even if the family members of the detainees want to inquire, the detention center cannot confirm the identity of the inquirer on the phone, and will not inform the relevant information for security reasons. Therefore, it is recommended to bring your identity documents and go to the detention center for face-to-face questioning.

Legal basis: Article 83 of the Criminal Procedure Law of People's Republic of China (PRC). 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.
