China announced Monday they have arrested more than one person at a temporary police checkpoint on a mega cross-border bridge, including a Hong Konger who was reported missing over the weekend by his family. It is the first time mainland officers have confirmed arrests on the artificial island that connects an enormous tunnel and bridge system linking Hong Kong to the cities of Macau and Zhuhai on the other side of the Pearl River Delta. The man’s son told local media Saturday that after his father had texted to say he was being detained at a mainland police checkpoint he had been unable to find out what happened and had filed a missing person case with Hong Kong officers.
