The 'Made From Crime' initiative will allow internet users to report their concerns online, anonymously if they wish, through an advert on the site.

It is the first scheme of its kind in Scotland, and has the backing of the Scottish government, the Crown Office and Procurator Fiscal Service.

It makes use of the Proceeds of Crime Act, allowing officers to seize assets.

Assistant Chief Constable Iain Livingstone, of Lothian and Borders Police, said: "We know there are people living beyond their means on the proceeds of crime, be it through the purchase of flash cars, designer clothes or expensive jewellery, and that communities are suffering from the side effects of drug dealing, violence and other associated crimes.

"I personally appeal to local communities who have any information to come forward immediately, either to Crimestoppers or to Lothian and Borders Police.

"Similarly, I would assure people who are trapped by those threatening them with violence or retribution, either associates or partners, that we will help them and tackle the violence and criminality they face.

"We will act on intelligence and bring offenders to justice."
