Students attempted to throw milk at former US President Joe Biden at Trinity College earlier.
Gardaí and a small group of protesters were involved in a standoff this evening.
It all kicked off when former US President Joe Biden made a surprise appearance at Trinity College earlier where his son Hunter Biden was being given an award by the College's Historical Society.
When it emerged the 83 year old was on campus a protest began with students highlighting his record on Gaza - and shouting slogans like Genocide Joe.
The protest escalated when the former President went to leave Trinity College - with some throwing milk cartons at Joe Biden which were stopped by the umbrellas of his security team.
At least one arrest was made - and student newspaper the University Times reports pepper spray was used.
Later in the evening as gardaí moved one arrested man to the public order unit van, the protesters attempted to stop the van leaving the premises by standing in front of it.
After a standoff gardai removed multiple protesters from their way and left the scene.
Former President Biden also met the Taoiseach Micheál Martin earlier at the Merrion Hotel - where they discussed Northern Ireland, international affairs and Mayo's All Ireland win.
