Protestors hit out at Bertie Ahern during a ceremony in DCU earlier today.
The Connolly Youth Movement have since uploaded footage of the incident to Twitter. The ceremony awarded both Bertie and peace campaigner Professor Monica Williams honorary doctorates for their work on the Good Friday Agreement, 25 years on from its initial signing.
A representative of the group interrupted from the audience after Bertie took to the podium to begin his speech. The unnamed protestor said that he could not let the event go ahead unchallenged and hit out at the Fianna Fail politician.
