The case was recently re-opened by the Police Service of Northern Ireland and a murder investigation started following a re-examination of the available evidence. Mr Cunningham had a fear of men in uniform and was running away from an Army patrol when he was shot. The Government apologised for his death in 2013.

He had a fear of men in uniform . Victims campaign organisation the Pat Finucane Centre (PFC) issued a statement on the family's behalf. 'Whilst family members have cautiously welcomed the arrest, they have asked the PFC to state categorically that they will only have confidence in an investigative process that is completely independent of the PSNI,' said a PFC spokesman. 'Cunningham family members said in October 2013 that they wish to see all investigations into British Army killings, including that of John Pat, being investigated by an independent body.' The investigation into the shooting was re-opened in March this year. Speaking in March, DI Neil McGuinness of the PSNI said: 'I appreciate this happened more than 40 years ago but I believe there are people in the community today who remember this tragic incident, who knew John Pat and who may have information which would be of assistance to the investigation. 'Our objective is to get to the truth of what happened that Saturday morning so that justice can be served.' The Government apologised for his death in 2013. A police investigation was re-opened earlier this year . Sorry we are not currently accepting comments on this article.
