Michael Keane, 29, has pleaded guilty to charges of assaulting a frontline community service provider, escaping from arrest or custody, and possessing a knife without a reasonable excuse.

Court documents reveal police were called to a home in Curtin just after 12.30am on November 19, following reports a man had "smashed up the house" and was "threatening to stab people".

When officers arrived, they found a broken window and three people yelling at Keane to "give back the keys".

"[Keane] was not wearing a shirt, appeared to be highly intoxicated, [and had a] bloodied hand and scratches to multiple areas of his upper body," court documents say.

Suspecting Keane had committed a crime, officers told him he was under arrest and tried to handcuff him.

But the 29-year-old "struggled and fought against police", eventually breaking free and taking an officer to the ground as he fled.

He hid in a nearby bush and, when he was found and told to stay there, he yelled: "I'm gonna shoot you. I've got a gun."

Keane held his hand out and pointed it at police, prompting officers to draw their guns and aim them at him.

Undeterred, Keane began walking towards the officers in the dark and saying he had a gun, putting his hands behind his back and into the pockets at the back of his shorts.

He was eventually Tasered twice and apprehended, having yelled after the first time: "Have a go. I'll f---ing shoot you, c---."

Keane continued to taunt police and call them "c----" as they searched him and found a small steak knife in the pocket he had been reaching into earlier. There was no gun.

He later had a seizure while in custody at the ACT watch house, prompting police to take him to Canberra Hospital for treatment.

There, he pointed his fingers at officers in the shape of a pistol and said: "I'm gonna put a bullet between your eyes."

Keane was listed for sentence in the ACT Magistrates Court last Thursday afternoon, when his Legal Aid lawyer Jan de Bruin said the offences had "coincided with the State of Origin".

He said Keane had wanted to attend a residential alcohol and drug rehabilitation program to address the cause of his criminality, but there had been nothing available at the time as a result of COVID-19.

Dr de Bruin said Keane had therefore, despite the best of intentions, been unable to stay away from substances and got himself riled up within hours of going out with some friends to watch the rugby league.

The lawyer asked Magistrate Louise Taylor to consider adjourning the sentence proceedings and granting Keane bail so the man could attend a 16-week rehabilitation course at a facility in Nowra, where a spot was now available for him.

Dr de Bruin said if Keane came back to court as "a success story", he would ask for "a closely supervised" sentence to be served in the community.

"If he fails, your honour, he's ready for the consequences associated with that," Dr de Bruin said.

Prosecutor Elizabeth Wren said Ms Taylor should remain "guarded" about Keane's prospects for rehabilitation given his history of violent offending.

She also said he had been given the opportunity of an intensive correction order, which is a community-based jail sentence, for other offences only a month before the incident in question.

Ms Taylor, who said she needed time to think about whether Keane should be granted bail, adjourned the case until Wednesday.
