Two men brandishing guns were photographed at Carlisle Parade in the New Lodge on Monday night.They were standing at a gable wall which had graffiti daubed on it stating: "Action against drugs, drug dealers will be shot".Victims' campaigner Raymond McCord told UTV: "I was out on the street. One of them came over to me and told me to shoot it - to take photographs of it."It was a frightening experience when you see a dozen or so hooded men and several of them carrying handguns."Mr McCord said that he believed the group behind the threat 'Action Against Drugs' are Republican paramilitaries."In the Nationalist areas, there's a major drugs problem. Some people see this as a way of dealing with the drugs problem - they shoot the drug dealers or people associated with them."They say people in this area are selling drugs - they know who they are and they intend to shoot them."A PSNI spokeswoman said: "Detectives in north Belfast are investigating an alleged incident whereby armed men used paint to write a statement which was threatening in nature, on the wall of a residential property in the New Lodge area on Monday night at around 9pm."Police would ask anyone who witnessed this incident or who has any information to contact detectives at Tennent Street on the non-emergency number 101, or anonymously to the independent charity Crimestoppers on 0800 555 111."
