An analytical report on collusion in what has become known as the Glenanne Series

Mr Boutcher said: “The review of the Glenanne Gang Series will have the interests of the victims, and their loved ones at its very heart.

“I have started to meet with the families and their representatives, and have promised each of them that I will do everything I can to establish the truth about who was responsible for these terrible crimes. For the families that especially means finding out about what, if any, assistance was given to the Glenanne Gang by others in any manner whatsoever, and that will include whether people turned a blind eye to what was happening.

"If anyone has any information about these crimes please do contact me through the Op Kenova website. Any inquiry or investigation is only as good as the information it receives. The Barnard Review will seek to recover records and information from wherever such information might be held, not only from PSNI records.

"I make a plea in asking the media to act with great care in reporting this Review, please consider the families’ feelings, respect their privacy and act with care when showing images. It is incredibly traumatic for families, friends and loved ones to see film footage and images from these tragic events."
