Mass murderer Salman Abedi had 'talked about killing people in a public space' for years before he detonated a bomb at Manchester Arena, the public inquiry into the atrocity heard.
But, the inquiry heard, Abedi spoke about it 'so often' that it wasn't 'taken seriously' and dismissed as 'hearsay' by those who knew him.
A prison officer, who cannot be named for legal reasons, gave evidence on Tuesday (February 15).
