The police checked the hotel records privately.

Hotel registration information belongs to personal privacy, and public security organs cannot check it at will. If it is necessary to investigate certain facts in handling a case, it can be inquired according to law after being approved by the leaders, and the inquiry records shall be kept. Hotels are special industries that need special management. Public security organs are the management units of specialized banks and have the right to inquire about registration information at any time. Article 56 of the Law on Public Security Administration Punishment stipulates that hotel workers who fail to register the names, types and numbers of identity documents of the guests staying, or who knowingly fail to stop the guests from entering the hotel with dangerous goods, shall be fined between 200 yuan and 500 yuan. Hotel workers who know that the overnight guest is a criminal suspect or wanted by the public security organ and fail to report to the public security organ shall be fined between 200 yuan and 500 yuan; If the circumstances are serious, he shall be detained for not more than five days and may be fined not more than 500 yuan.
