10 bin protesters sent to Mountjoy
Mr Mahon, from Finglas in north Dublin, was one of 10 protestors, including two grandmothers and a breast-feeding mother, sentenced after they refused to give an undertaking that they will not blockade waste lorries.
Five men and four women were given two weeks in prison by the High Court. A 10th, Lisa Carroll, was sentenced to a week, after the court heard she was still breastfeeding. They join politicians Mr Joe Higgins and Ms Clare Daly in Mountjoy.
