Police are appealing for witnesses after thieves stole copper cabling valued at around £6,000.
The incident happened in the Peterhead area at around 1.15am on Saturday.
PC Calum Stewart said: “It is believed a large vehicle would have been required to remove the cabling and we are appealing for anyone who saw anything unusual or suspicious in the area, particularly the A90 between Boddam and Peterhead, to contact police.
“We would also ask that anyone who was driving in the area and may have dashcam footage to contact us, even if they may not think they have captured anything.
“Police can be contacted on 101 using reference number 1074 of 30 July. Crimestoppers can also be contacted on 0800 555 111 to remain anonymous.”
