This morning, police issued an appeal public assistance to help locate Emily-Rose King who is from the Northern Beaches area.

The 13-year-old was last seen leaving a medical facility at St Leonards in Sydney’s north on Thursday. But, around 12pm today she was found safe and well in Brisbane by Queensland Police.
