West Yorkshire Police are appealing after a large amount of specialist equipment was stolen from an address in Todmorden.
The force are asking "Anyone offered specialist climbing equipment, parachutes and other outdoor gear for sale in a deal that sounds ‘too good to be true’ to get in touch with police."
The appeal comes after a large amount of valuable items were taken during a burglary at an address on Nutfield Street, Todmorden.
Police say the incident happened on a date and time unknown between Monday, April 8 and Wednesday, April 17.
All of the equipment, including some power tools, was taken from a store room inside the property.
DC Craig Pearson of Calderdale CID, said: “Given the amount of equipment taken we suspect the thief of thieves will have used a van to transport the goods and taken a long time to move them from the property.
“The items are also highly specialised so I would urge anyone with a particular interest in outdoor activities including climbing / mountaineering, mountain biking, caving, canyoning and parachuting to get in contact.”
Anyone with information is asked to contact police on 101 quoting crime reference 13190204590
