"Our members of staff come into work to care for vulnerable, sick and injured people, and although it is relatively uncommon, we will not tolerate intimidation, threats, or physical violence.

The number of assaults on hospital staff peaked in 2011 when there were 116 incidents across the trust. Since then the number fell to 87 in 2012 and 68 in 2013.
