The British Army’s alleged highest-ranking spy in the Irish Republican Army (IRA) has been arrested and is being questioned about his involvement in dozens of murders
Fred Scappaticci, the man understood to have been arrested had previously admitted to being a republican but stopped short of confirming claims about being an IRA informant.
Mr Scapaticci’s arrest is part of the investigation into the activities of current and former members of the police force, Army, MI5 and IRA.
