A fake speed camera built by two teenage brothers has been credited with halting speeding motorists along a country lane.
The camera was taken down on Tuesday
The schoolboys erected the cardboard fake in a bid to put the brakes on cars driving through the village of Lepton near Huddersfield.
The "camera" was built from a cardboard box, painted yellow, and some scrap timber.
George Guest, 14, and his 13-year-old brother Freddie even placed strips of duct tape along Gawthorpe Green Lane to act as official looking road markings.
Their father Denton said: "It started off as a practical joke by my two sons but has
developed from there.
"They decided to build a better, improved version on Sunday and the results have been just as impressive.
"Motorists use the road as a rat-run in the morning and evening and it is a dangerous road.
"It is incredible that a simple yellow box could be so effective."
Mr Guest said the fake camera was dismantled on Tuesday, but said he was "100% sure" another one would soon appear.
Despite looking authentic from a distance the device does not contain any photographic equipment.
Philip Gwynne, of the West Yorkshire Casualty Reduction Partnership, told BBC News Online: "As far as we're concerned this demonstrates that people increasingly recognise the benefits and effectiveness of safety cameras.
"It shows they make roads, and the communities along them, better places for everyone."
