An attempt by local council snoopers to catch fly-tippers backfired when a surveillance camera hidden in a black rubbish bag and worth around £10 000, was collected by binmen and thrown away.
The council would not say whether recordings had been lost or where the site is located.
A council spokesman snootily said:
"We are required to consider whether the public interest in disclosing the information outweighs the exemption. But we consider that as there are on-going difficulties with this site, the investigation should take precedence."
