Louise Allison Langhorn died in hospital last week after receiving injuries believed to have been sustained during an altercation in Balga this month.

Sergeant Alice Cockram said Louise Allison Langhorn told police she was assaulted by a group of men on Wednesday, February 6, on Balga Avenue near Redcliffe Avenue.

She did not immediately report the assault, but told police about it at a later stage and was admitted to Royal Perth Hospital two days after suffering injuries in the incident.
