Investigation launched after Oberstown 'locked-down' over stand-off with armed inmates
Two youths were involved in a stand off with more than a dozen riot police at Oberstown detention centre on Monday night.
The two teenage males were standing on top of a roof near the front entrance of the centre.
Three garda public order units, two garda cars and a Dublin Fire Brigade were called to the scene.
Members of the gardai were understood to be negotiating with the pair to come down from the roof, with a ladder placed at the wall leading down.
It's believed the two young men took a swipe card from an employee at Oberstown and gained access to weapons such as screwdrivers, blades and drills.
Part of the campus is on lock-down following the incident.
Gardai confirmed they are investigating am ongoing incident in Oberstown but would not provide any further detail until the issue has been resolved.
