A number of fallen power cables have forced police to closed Abbotsham Road near Bideford.
Police were called to the Moreton Park Road area at around 8.45am after a member of the public reported live power cables in the road.
Officers immediately shut the road due to safety reasons and contacted Western Power Distribution.
Engineers from Western Power attended the scene and cut off the power supply. At least one property is currently without power while engineers work to repair the overhead cable.
A spokesman for Western Power Distribution said the cable appears to have “rusted” or “come away” from the overhead line.
Power is expected to be restored to properties within the next hour.
The road remains shut at this time and motorists are advised to seek an alternative route.
