Media regulator Ofcom has launched an investigation in to how ITV managed to mistakenly present footage of Arma 2 as a secret IRA propaganda film from 1988.
The documentary clip - which was aired late last month - showed 'a helicopter being shot down by the IRA using weapons supplied by Colonel Gaddafi'. It was in fact fan-made Arma 2 footage.
Ofcom told The Guardian this morning it's now launching an investigation to see whether the incident constituted a breach of its broadcasting code.
ITV has since apologised for the cock-up, blaming the Arma 2 inclusion on an editing mistake.
In a statement, it said: "The events featured in Exposure: Gaddafi and the IRA were genuine but it would appear that during the editing process the correct clip of the 1988 incident was not selected and other footage was mistakenly included in the film by producers.
"This was an unfortunate case of human error for which we apologise."
