On the evening of May 22, the official Weibo of the Changping Branch of the Beijing Public Security Bureau released a briefing:

Recently, the Changping police reported to a nucleic acid testing agency that during the inspection of the nucleic acid collection business, someone was found to be on the job with a fake nurse practitioner certificate. After investigation, the suspects He Moumou (male, 35 years old) and Yin Moumou (male, 36 years old) were applying for work related to nucleic acid collection, and fraudulently obtained qualifications for nucleic acid sampling by forging and purchasing false nurse practitioner certificates.

On May 21, when the two people participated in the sampling work at a nucleic acid testing site in Shisanling Town, Changping District, the inspection staff of the testing agency discovered that their qualifications were fraudulent. The two people were later arrested by the Changping police. At present, He Moumou and Yin Moumou have been taken criminal compulsory measures by Changping Public Security Bureau in accordance with the law, and the case is under further work.

For unqualified personnel who use false professional qualification certificates to participate in nucleic acid collection, testing and other work, and interfere with the development of epidemic prevention work, the police will severely crack down on various illegal and criminal acts.
