If a lawyer is entrusted to report a case to the public security organ, the public security organ may require the informant to accept the inquiry.

What you want to ask is to entrust a lawyer to report the case to the public security organ. Can the public security organ request an interrogation of the informant? Must be accepted. The Lawyers Law of People's Republic of China (PRC) stipulates the specific business that lawyers can engage in. In the case of reporting to the public security organ, the victim should report to the public security organ, because the staff of the public security organ will directly ask the victim some questions. You can't entrust a lawyer to report the case. Reporting a case is not within the scope of lawyer's business, and it is carried out by the parties or their close relatives.
