Deputy police commissioner Catherine Burn says that the five hostages who left the cafe "are now being assessed to make sure their health is okay and then police will talk to them". She would not confirm how many are left in the cafe.
Here are images from earlier of two women who fled the cafe. They were wearing brown uniforms with the Lindt logo.
New South Wales deputy police commissioner Catherine Burn told reporters she cannot confirm demands by the gunman as reported by media outlets. "We have to deal with him on the level of police negotiation. We cannot engage in speculation."
If you are just joining us, the latest situation is that armed police are surrounding the cafe and officers have made contact with the gunman. Five people have been seen running from the building but it is not clear how many remain inside. A black Islamic flag has been displayed at the window.
