An investigation into the death of a 95-year-old woman who died after a care home assault will continue after a post mortem examination proved inconclusive.

May Miller died on Sunday, February 16, a week after she was assaulted at Beech House care home by another resident.

Police officers were called to the care home on February 9 following reports of assault, and assisted Mrs Miller who had been beaten with a metal walking stick by another resident, believed to have dementia.

Mrs Miller was hospitalised following the assault, which left her with fluid on her lungs, coughing up blood, and with a chest infection, her family say.
