Relatives of the Claudy bomb victims have said they are shocked at a PSNI decision to suspend the investigation.
Some of the victims’ families met with Chief Constable Matt Baggott on Friday when he informed them there would be no further action unless new evidence came to light.
A victims’ group representing a number of families affected by the atrocity has made a fresh appeal for information in the hope of reversing Mr Baggott’s decision.
A spokesman for Justice For Innocent Victims of Terrorism (JIVT) said the families would pursue “all legal means open to them” in their search for the truth.
On July 31, 1972, three bombs ripped through the Londonderry village of Claudy killing nine civilians aged between eight and 65.
The JIVT spokesman said: “A meeting was held with families and other interested parties on Friday last and to say that there was shock within the room when the PSNI revealed their intention to suspend the investigation would be a gross understatement.
“To think that over 41 years have passed since this high-profile bombing yet no-one has yet been brought to justice or held criminally accountable is an indictment of not only our criminal justice system but also of a community which wilfully harbours those responsible.”
The spokesman added: “Claudy was a crime against the community perpetrated by the Provisional IRA and it is essential that those responsible are held publicly and personally accountable for their actions.”
Ulster Unionist MLA Tom Elliott accompanied the Claudy families to Friday’s meeting and afterwards said there were concerns “political interference” was preventing the full facts emerging.
“The news that the police have suspended the investigation due to a lack of evidence and information was met with a mixture of frustration and anger,” Mr Elliott said.
Commenting on the families’ concern, a PSNI spokeswoman said: “Police can confirm that we met with Tom Elliott and members of the families to update them on the investigation and to inform them we have completed our inquiries identified from a review. As a result, the investigation is currently suspended until such times as new information or evidence is received.”
She said the PSNI is continuing its appeal for information “so that the people responsible for this atrocity are brought to justice”.
