The PSNI has uncovered a security-force link to the murder of a Co Donegal teenager in Belfast 35 years ago. The PSNI's Historical Inquiries Team has been re-examining the killing of 16-year-old Henry Cunningham during a UVF attack on building-site workers in 1973. Its report into the matter says one of two machine guns used in the attack was stolen from a UDR base in 1972 and intelligence files point to strong evidence of security-force collusion in the weapons theft. The Cunningham family say they are shocked by the revelation and have criticised the fact that the Irish Government apparently made no representations to the Northern authorities in relation to the murder. Henry Cunningham was apparently targeted along with his brothers because the UVF thought they were Catholic, but they were in fact Presbyterian.
