Ian Bailey claims Gardai told him paramilitaries would kill him with a bullet to the back of the head if he did not confess to the murder of French beauty Sophie Toscan du Plantier.
He makes the allegation in the second episode of his new podcast to be broadcast this week, Paradise Found, Paradise Lost.
He said he was given the warning by a senior officer who he named when he was first arrested over the shocking Christmas 1996 killing.
