Referral to prosecutors comes as UK told plan to end Troubles prosecutions ‘could breach international law’

A former police officer of the Royal Ulster Constabulary (RUC) has been referred to public prosecutors in Northern Ireland in relation to a series of potential offences including the sectarian murder of three brothers.

John Martin, 24, Brian, 22, and their 17-year-old brother, Anthony Reavey, were shot by the notorious loyalist Glenanne gang at their home in County Armagh in 1976.
