Jimmy Guerin, a brother of murdered journalist Veronica Guerin, claims in a High Court action that Gemma O'Doherty defamed him in social media posts and a website video which he claims meant he was a convicted paedophile.

Mr Guerin is suing Ms O'Doherty, a former journalist with the Irish Independent, over the postings on Twitter (X), Facebook and her own internet video broadcast portal, Gemma.TV, on July 11 and 12, 2019.
