Chinese authorities last week discovered an underground tunnel connecting Hong Kong to the mainland that was reportedly built by smugglers to avoid border fees and taxes.
The ventilated concrete tunnel includes lights and rails for transport goods, authorities said. It starts under a garage in Changling village, near Shenzhen, and stretches as far as 40 meters under a river and into some concealed reed-beds in Hong Kong, BBC reports.
Authorities believe that gangs were using the tunnel, which cost an estimated 500,000 USD to build, to smuggle in cell phones and electronics from Hong Kong. It was discovered after a resident complained about loud drilling noises going on for an extended amount of time near her home.
Officials believe the tunnel was 20 meters short of its intended destination in Hong Kong. It has since been destroyed and one man has been arrested in connection to its construction.
“It was dug in a totally professional way,” authorities said in an AFP report. Still small potatoes next to the government’s proposed 260-billion yuan undersea tunnel connecting Dalian and Yantai.
