A school principal has paid tribute to the eldest victim of a violent incident in Dublin which took the lives of three children.

The three victims have been named as Lisa Cash, 18, and her eight-year-old twin siblings Christy and Chelsea Cawley. The principal of St Aidan’s Community School, Kevin Shortall, said the community was in shock following the incident.
