Alfredo Scappaticci, the former provisional IRA informer codenamed Stakeknife.
Freddie Scappaticci was not hauled in for interrogation by the IRA when he was suspected of being an informer.
This was in 1990, after the RUC raided a house where the Provos were holding another suspected informer, Sandy Lynch. Scappaticci had been interrogating Lynch at the house as part of the IRA’s internal security unit, even though he was a British agent himself.
