RUC Special Branch used UDA/UFF members as informers despite them being linked to crimes including murder, an investigation has found.
The finding is just one of a catalogue of failings unearthed by a Police Ombudsman probe of a series of murders and attempted murders in South Belfast in the 1990s.
The 344-page report considers police actions in relation to eight loyalist attacks in which 11 people were murdered, including five people murdered at the Sean Graham Bookmakers on the Ormeau Road on February 5, 1992.
