Builders unearth €9m gold stash sealed in walls of Belgian property

The construction workers stumbled across the hidden trove of gold bars and coins while drilling to lay new sewage pipes in the property in east Flanders earlier this week, local media report.

After launching an investigation, police warned people against attending the site to search for more treasure, saying the house was "turned upside down" and all the gold had been moved to a secure location.

Local police urged the public not the active construction site looking for treasure.
