The author of the QQ Coral Bug version was arrested, and I have a question.

After reading the relevant reports, I have a question that I don't understand: Generally, criminal cases are under the jurisdiction of the authority where the criminal act took place. Article 15 of the "Regulations on the Procedures for Public Security Organs Handling Criminal Cases" issued by the Ministry of Public Security stipulates that "Criminal cases shall be under the jurisdiction of the public security organ where the crime was committed. If it is more appropriate for the public security organ where the suspect resides to take jurisdiction, then the latter may have jurisdiction." Isn't Mr. Chen in Beijing? Last year's civil litigation was also under the jurisdiction of the Beijing court, so why did the Shenzhen police handle this case this time?
