Far right activist Graham Carey has been charged under the Offences Against the State Act and is due in court this morning.
The 39-year-old was arrested at his Finglas home on Wednesday morning by members of the Special Detective Unit within the Gardai. It is understood the arrest followed a lengthy investigation.
In a video shared widely online, Mr Carey claimed anti-refugee protestors would "go through" Finglas Garda Station on Wednesday night. He is considered a leading voice in the anti-immigrant protests that have sprung up around the city.
