A 61-year-old woman has been arrested and charged as part of an ongoing investigation into allegations of assault at a Perth aged care facility.
Western Australia Police allege the woman assaulted a 92-year-old resident at the Midland facility on seven occasions.
Last week, a 38-year-old female staff member was charged with five counts of aggravated common assault.
Both women are due to appear before the Midland Magistrates Court later this month.
