Vandals used a blowtorch to destroy a replacement speed camera within a few hours of it being erected. The camera in Milton Keynes was put up to replace one stolen in Watling Street, Fenny Stratford, last year.
But by the end of the day the camera was spotted hanging from its metal pole - having apparently been attacked with a blowtorch.
Action group Motorists Against Detection - led by "Captain Gatso" - has claimed responsibility the act.
A spokeswoman for Milton Keynes Borough Council said they were still waiting to see how much the attack had cost.
Surveillance plan
"The camera was left hanging," she said.
"Usually they take them but we think they might have been disturbed.
"We don't know how much the new one cost - we haven't even had the bill yet."
The attack is the fourth in as many months in the area.
The council and police said they would be using surveillance to catch the culprits.
