A family friend, who had just taken away Miss Spencer's two younger daughters for their safety, died after being caught up in the assault in south London. She is believed to have been in her thirties but has not yet been named by police. Miss Spencer was stabbed in the stomach while one of her daughters, 22-year-old Stacey, is believed to have had a finger cut off while trying to protect her mother. Both are in a serious but stable condition in hospital.
