The 40-year-old, nicknamed Mad Dog, is believed to be armed.

He is is wanted for breaching a supervision order several days ago and for allegedly assaulting his partner last weekend.

Loguancio emerged from the property yesterday with something strapped to his chest, but police could not confirm whether it was a weapon.

They sent a remotely-operated robot into the house yesterday and heavily-armoured officers continue to wait outside.

There was concern earlier that Loguancio would go through with threats to burn down the property.

Police have cleared the way for the Metropolitan Fire Brigade in case things get out of hand, as they continue to negotiate with Loguancio.

The situation remains tense, but police say they are willing to be patient for a peaceful outcome.

They have been trying to keep Loguancio awake with sirens and have been communicating with him via telephone.

It has been reported Loguancio, one of Victoria's most wanted fugitives, has a criminal record that includes six counts of rape, five of intentionally causing injury, four of making threats to kill and 12 of common assault.
