A female hospital staff member was stabbed to death in a "tragic" incident, an NHS Trust has said.
A spokesman for 2gether NHS Foundation Trust, which runs the acute mental health hospital where the attack took place, said:
During the incident a colleague was stabbed and after being attended by fellow clinicians, was taken to Gloucestershire Royal Hospital.
It is with deep sadness that we confirm that our colleague died a short time later. Our thoughts remain with their family and friends at this extremely difficult time.
"The full facts of this sad incident are still being established and therefore it is inappropriate for us to comment further at this time.
The spokesman was unable to confirm the role of the staff member, but it is understood that she was not a nurse.
