Calderdale police took part in a national operation on Wednesday to tackle metal theft.
Four local scrap metal dealers in Calderdale were visited to carry out extensive checks and give advice.
Officers also conducted patrols in hotspot areas for metal theft and stopped 12 vehicles carrying scrap metal to check documents.
Nothing suspicious was found in Calderdale.
Sgt Dean Maddocks said: “Metal theft causes untold misery to local residents, commuters and in some incidents, a danger to the public. In many cases the cost of damage and repairs far out weighs the scrap value of the metal.
“Despite the poor weather conditions we were able get out there and offer advice to businesses, reassurance to the public and gather intelligence by stop checking vehicles carrying scrap metal.
“We urge the public to contact us if they see any suspicious activity with these vehicles in our local communities.”
Anyone who suspects metal theft should contact police via 101.
