Three students were removed from the new student centre in UCD after two eggs were thrown at Taoiseach Enda Kenny during the building's official launch.
Although neither egg hit Mr Kenny, one reportedly hit UCD's vice president for students Martin Butler.
A spokesman for the university said that it is likely the three students will receive sanctions under the university’s code of conduct, but that the event went ahead as planned.
“The incident took place just before he spoke, but he continued on and met the crowd afterwards,” he said.
Student group Free Education for Everyone (FEE) has taken responsibility for the incident, with a spokesman saying students have been badly hit by Government actions.
"Vulnerable members of society have been targeted consistently throughout this economic crisis. Students have been a part of this attack, leading to mass graduate unemployment and emigration. We vehemently oppose this approach by Fine Gael and Labour."
The new student centre includes a 50 metre Olympic-specification swimming pool, a purpose-built debating chamber which resembles a mini-parliament, a fully kitted out performance theatre, a multimedia 3D cinema and a dance studio with a floating floor.
