Violent attacks in the region's prisons have risen sharply in the last six years, according to figures obtained by the BBC.
Boiling water and battery acid are some of the things which have been used as weapons against staff.
Between April 2011 and August 2017 research has revealed there were more than 200 attacks on officers, inmates and visitors, 17 of which caused serious injury at the high security Long Lartin prison in Worcestershire.
