The most senior police officer in the north west has admitted his officers are struggling to secure convictions against the republican vigilante group Republican Action Against Drugs.
The group have carried out numerous punishment style attacks in the Northwest in the past year, and a number of men have been ordered to leave Derry.
Chief Superintendent Steve Martin said there had been a couple of convictions but insisted the public had a vital role to play in helping the police.
He said the organisation was a small group made up of former paramilitaries who intimidated people.
Meanwhile, The North’s Deputy first minister has called on people in Derry to help police jail members of RAAD.
Martin McGuinness said he hoped people would come forward “ to give all the information they have about this group.”
