...in the several weeks beginning in mid-February 2004, when, slowly at first but with mounting velocity, manhole covers started to disappear from roads and pavements around the world. As Chinese demand drove up the price of scrap metal to record levels, thieves almost everywhere had the same idea. As darkness fell, they levered up the iron covers and sold them to local merchants, who cut them up and loaded them onto ships to China. The first displacements were felt in Taiwan, the island country just off China's southeast coast. The next were in other neighbors such as Mongolia and Kyrgyzstan... Wherever the sun set, pilferers worked to satisfy China's hunger. More than 150 covers disappeared during one month in Chicago. Scotland's great drain robbery saw more than a hundred vanish in a few days. From Montreal to Gloucester to Kuala Lumpur, unsuspecting pedestrians stumbled into holes.
