No one checked the foot bath plane because no one called the police. The reason for not catching it is that no one reported it or someone reported it. Because the circumstances of the case are obviously minor, there is no need to pursue criminal responsibility, so the arrest is not approved. The people's procuratorate or the public security organ shall, within its jurisdiction, timely examine the materials of accusation, accusation and surrender, and if it considers that there are criminal facts that need to be investigated for criminal responsibility, it shall file a case. If it is considered that there are no criminal facts, or the criminal facts are obviously minor, and it is not necessary to pursue criminal responsibility, the case shall not be filed, and the complainant shall be informed of the reasons for not filing the case. If the complainant refuses to accept it, he may apply for reconsideration.
