During the campaign, which runs until Sunday, May 29, people can surrender any unlicensed or unwanted firearms and ammunition to the police by calling 101 to organise an appointment.
People will not face prosecution for possession of the weapon at the point of surrender – and can also remain anonymous.
But it’s not a get out of jail free card – as weapons that police link to criminal activity will be investigated and appropriate action taken.
Superintendent Mike Todd said: “Many firearms are held in innocence and ignorance of their illegality or are overlooked and forgotten in people’s homes. Some are held legally and are no longer required.
“Surrendering unwanted, unlicensed, and illegal weapons avoids the risk of them becoming involved in criminality and means that members of the community can dispose of firearms in a safe place.”
