Police are investigating after images appeared online showing a group of masked men in Co Antrim alongside IRA graffiti warning drug dealers to leave the area.
DUP MLA Pam Cameron has urged police to urgently investigate the pictures, saying the photos were linked to a paramilitary group and had left residents living in fear.
Photos emerged on social media of men standing outside Ballydonaghy Meadows in the Crumlin area wearing camouflaged jackets with their faces covered, holding what looks like some kind of firearm.
One of the pictures is captioned RAD with a tricolour.
Graffiti also appeared in the area warning IRA territory drug dealers out .
The mother of a man murdered in cold blood nine years ago said the pain of knowing his killers are free to walk the streets of Londonderry is becoming more unbearable every day.
Andrew Allen (24) died almost immediately after being shot three times by a dissident republican gunman on February 9, 2012 at his home in Buncrana, Co Donegal.
Mr Allen was shot in front of his partner at approximately 9.20pm and pronounced dead at the scene. A car believed to be involved in the murder was found on fire at Churchbrea, Fahan, three miles outside Buncrana, shortly after the shooting.
Mr Allen had moved out of Derry a number of months earlier after receiving death threats alleging he was a drug dealer - something his family have vehemently and consistently denied.
