Hong Konger 'missing' after crossing China bridge checkpoint

Hong Kong's immigration department said Sunday they have received reports a man went missing on a cross-border mega bridge to the gambling hub of Macau that currently hosts a Chinese mainland police checkpoint.

The disappearance first emerged on Saturday when the man's son told local media his father had texted to say he was being detained while passing through an artificial island manned by Chinese police on his way to the semi-autonomous city of Macau.

The man, surnamed Chan, was travelling by bus on Friday afternoon along the bridge and tunnel network linking Hong Kong, Macau and mainland city Zhuhai, his son said.

"His last message said 'I got arrested'," the son told Cable News.

The artificial island in the middle of the Pearl River Delta lies in Chinese mainland waters.

Mainland police set up a new checkpoint there last week with X-ray machines and facial recognition checks ahead of an upcoming visit to Macau by President Xi Jinping.
