Belgium, where the sretts are paved with ......... cast iron (image source)
The Belgian city of Charleroi has been hit by a spate of drain-cover thefts because of rising metal prices. About 70 sewer lids made from cast iron have vanished since Thursday of last week, an official at the town hall said. A 40kg sewer lid can be sold on the black market for roughly e6 (£4), the official said. "We have put pressure on resellers of metals and warned them they will be prosecuted if they are found with lid covers," he said.
As they say in my part of the world "where there's muck there's money."
