Can anyone give me advice please? My mother who has advanced dementia is resident in a care home. One of the staff was recently prosecuted for physically abusing mother. However the case could not be proved because of differences in evidence provided by other members of staff. I am very worried that the person concerned will be able to return to work and have direct contact with mother as well as the other member of staff who supported her. What would be my best course of action to protect mother?
