Retailers across Edinburgh are to help police stop stolen goods being sold to second hand shops.
Managers will contact others if someone tries to flog them suspicious items.
Officers have supplied stores with SmartWater lamps to detect if products have been marked by their owner.
"Tradewatch" was developed as a result of the continued engagement and dialogue between second-hand retailers and Edinburgh Division's Search and Recovery Team.
Detective Chief Inspector Stuart Houston said: "Those responsible for acquisitive crime will often attempt to sell on stolen goods for profit and regularly attempt to utilise second-hand retailers to dispose of valuable items.
"However, we have an excellent and long-standing relationship with these businesses in Edinburgh and staff regularly assist our Search and Recovery Team in reuniting stolen property with its rightful owner as well as helping us identify those responsible for the thefts.
"With the launch of 'Tradewatch', these premises will instantly and readily share information on any suspicious customers so that items that have been acquired illegally are not bought and sold within their stores.
"I would like to thank our second-hand retailer partners for their assistance and co-operation in helping to create this campaign."
Chief Inspector Richard Horan said: "Tackling housebreaking and robbery is a priority across the city and the 'Tradewatch' initiative is yet another tool in our armoury to bring those responsible for these crimes to justice.
"We continue to target and pursue those who steal through ongoing enforcement activity and partnership campaigns. The public also play a vital role in assisting us prevent these crimes, and making life difficult for criminals, by taking simple steps to safeguard their belongings.
"I would urge members of our communities to ensure their homes are always appropriately secured and that any items of value are stored safely out of public view. Details of the type of valuables within your property should never be disclosed to anyone you do not know or trust.
"Please remember that sheds, garages and other outbuilding are extensions of your home and should also be secured at all times.
"Our partnership with SmartWater Technology Ltd continues within the Capital and hundreds of homes have been issued with the unique chemical solutions to mark their property. However, additional home security measures such as alarms and motion-activated lighting should also be considered where possible. Your local community policing teams will be delighted to offer free crime prevention advice."
David Patrick, CEO of Cash Converters UK, the UK's largest second-hand retailer, said: "We're delighted to be working with the police and a part of the new Tradewatch scheme as we are committed to tackling the issue of stolen goods in our stores.
"We have a zero tolerance policy towards stolen goods and a number of processes in place to deter criminals. Anyone looking to sell an item to Cash Converters must present two forms of ID along with proof of address as per regulations set out by the Financial Conduct Authority. In addition they have to be photographed and sign an agreement confirming they are the legal owner of the goods.
