Dublin’s Lord Mayor Eibhlin Byrne will meet senior gardaí today after three people were arrested following disturbances in a north inner city housing estate.

Gardaí were today investigating what has been described as an embarrassing security breach at a building adjoining one of its most sensitive operational centres.

The Government today vowed a relentless war against gangland violence after an unarmed police officer was gunned down in Dublin.

INTELLIGENCE failures may have resulted in the gardaí being ill-prepared for Saturday’s riots in Dublin.
