When is the arraignment after criminal detention?

First of all, the Criminal Procedure Law stipulates that after you are detained in criminal detention, you should be arraigned within 24 hours. Public security organs must act in strict accordance with the law. If you have evidence that your friend has not been arraigned within 24 hours after being detained, you can lodge a complaint with the people's procuratorate. If the investigation proves to be true, the people's procuratorate will issue a Notice of Correcting the Violation to the public security organ. Second, your friend is suspected of theft. How many days of criminal detention depends on the specific case. Usually three or seven days is possible. If it meets the gang, it can be extended to 30 days several times. Finally, you said that your friend just bought a dirty car, but it still depends on the specific situation. If you participate in premeditated, prepared and committed theft, it should be theft, and the public security organ will commit the crime within 24 hours after detention.
