Police Scotland have introduced a tagging spray designed to deter and detect criminal behaviour.

The project is aimed at targeting offenders involved in motorcycle activity, anti-social behaviour and criminality through the use of SelectaDNA's tagging spray.

The handheld spray will be aimed at bikes, clothing and skin of any riders and passengers with a uniquely-coded but invisible DNA that will provide forensic evidence to link them to a specific crime.

When someone has come into contact with the solution, officers can use handheld lamps to detect the product on the person, clothing and footwear.

The spray is deployed as a fine mist which does not cause any harm or damage to skin or clothing.

Officers in Edinburgh have launched the project for the first time in this way in Scotland, and it has previously been successfully used to trace suspects by forces in England.

Edinburgh officers are aiming to use the spray to specifically target illegal motorcycle activity across the city.

Assistant chief constable Wayne Mawson said: "Illegal motorcycle activity has been an ongoing issues within Edinburgh communities for some time and the addition of SelectaDNA's tagging spray will help us to both deter and detect this type of behaviour.

"SelectaDNA's tagging spray can be sprayed by officers at bikes, clothing and skin of any riders and passengers, resulting in a uniquely coded but invisible dye, which can only be detected through special lights owned by police.

"It is essential that the public in Edinburgh continue to work with us to apprehend those taking part in anti-social behaviour and hold them to account."
