A 15 year old boy has been arrested after a terror threat made at a southside school.
Armed gardai were deployed to the scene at lunchtime yesterday.
They were alerted after two 999 calls were made by someone claiming they worked on behalf of ISIS and were planning to blow up the school.
A major garda response culminated in the arrest of a 15 year old boy at around 1.40pm.
He was taken to Sundrive Road Garda Station but has since been released without charge.
A file is being prepared for the DPP.
