A man has been arrested after allegedly threatening gardaí at Blanchardstown Garda station.
According to a Garda statement, the man entered the station in Dublin 15 shortly before 4am on Tuesday and made a number of threats.
Officers from the National Negotiators Unit, along with members of the Armed Support Unit, attended the scene. A cordon and local diversions were put in place.
The incident was resolved peacefully following negotiations.
The man was detained under the provisions of section 12 of the Mental Health Act 2001.
A media blackout – under which media organisations are asked not to report on the situation while efforts to resolve it continue – was also put in place but has since been lifted.
The roads that were closed have been re-opened.
No injuries were reported and investigations are ongoing.
