Allison Williams, chief executive of Cwm Taf University Health Board, says she recognises there is public concern over the ongoing investigation. She says the health board will work with police to "get to the bottom of what happened."
Cwm Taf University Health Board takes the care and safety of its patients extremely seriously. As soon as staff identified that there was a problem with the patient concerned, they acted quickly and appropriately. We are continuing to work with the police to do everything we can to get to the bottom of what happened.
We would like to emphasise that there is no suggestion that any other patients have been affected.
She added that anyone with concerns about the care of their relatives are encouraged to talk to ward staff who can arrange for them to speak with a senior member of the health board.
