3/11/2010 - About 60 prisoners aged between 15 and 18 refused to return to their cells at Warren Hill, in Woodbridge, Suffolk, at about 7.30pm on Tuesday.
After a stand-off Tornado response teams in riot gear went in at 0540 GMT and regained control, with no resistance being offered.
The wing at Warren Hill is understood to have suffered extensive damage.
All 138 of the young prisoners may be moved because a set of keys disappeared.
As a result all the locks may have to be changed.
