Gardai had to be called to Oberstown children's detention centre after a group of young offenders barricaded themselves in an area of the campus.
They were called to the campus yesterday at the request of staff when four of the juvenile inmates barricaded themselves into the kitchen area.
Along with local gardai, the public order unit also attended the scene.
