If the public security organ needs to inquire about personal chat information when handling a case, it will apply to the superior for approval, and then it can obtain the information records of the relevant personnel from the relevant units.
Under normal circumstances, if there is no corresponding case involved and the police have not produced a corresponding search warrant, then you can't randomly retrieve personal WeChat chat records. However, if a criminal case is a particularly important clue, the police can check the chat records.
Under what circumstances can the police retrieve chat records?
If the content of WeChat involves criminal cases, especially the investigation clues of important criminal cases, the public security organs at or above the county level may take technical investigation measures against the mobile phone number. This method can track the location of mobile phones, monitor calls and intercept WeChat. Within a certain period of time before the technical investigation means is started, the telephone and WeChat content will be saved to a company computer that provides communication services. Public security organs can only investigate criminal suspects after filing a case according to law, otherwise it is an illegal act of law enforcement. To investigate the chat record information of the user's WeChat account, you need to log in to the WeChat account, and then query the roaming record information of the user.
