Aer Rianta is investigating a breach of security at Dublin airport after a journalist with a multi-tool set of pliers, blades and screwdrivers in her handbag passed through X-ray checks undetected, writes Marie O'Halloran.

The Minister for Public Enterprise, Ms O'Rourke, said she met senior management at Aer Rianta yesterday after learning of the breach by TV3's Suzanne Coogan.
