Vito Jean Leclair, 46, was due to face court on Monday morning for breaching his bail after allegedly yelling "you're a dead man walking c--t" several times to two people last Wednesday who he was barred from intimidating, threatening, harassing or assaulting.

But the court heard Leclair, of Conder, was taken to Canberra Hospital in an ambulance after an "altercation" in the cells on Monday morning.

When Leclair appeared in court later in the day he had a small bandage on his arm and his defence lawyer said six cellmates had assaulted him "with their fists" leaving him with "various injuries".

In arguing for his client to be released on bail, Leclair's lawyer said he was concerned the unprovoked attack may occur again and Leclair was "scared" of further assaults in custody.

"It appears he's been subject to an orchestrated attempt to hurt him, the CCTV camera was deliberately covered," his defence lawyer said.

"My client is a vulnerable person having mental health issues and he's protected somewhat if he's allowed in the community with appropriate conditions.

"It was not just common assault, there were, and still are, injuries requiring hospitalisation."

But magistrate Peter Morrison denied Leclair bail saying he had to balance his safety with that of his alleged victims and Leclair had a history of breaching conditions.

Leclair was arrested last Wednesday when he allegedly yelled "you're a dead man walking c--t" several times to two neighbours, according to police facts.

Later in the day, as one of his victims got in her car, he allegedly walked towards her and tugged at his genitals "violently" through his clothing while laughing.

Mr Morrison said the allegations were "serious" and "bizarre" and caused him to question the efficacy of Leclair's mental health treatment.

"[But the mental health] treatment in the community is not treatment he couldn't otherwise have in custody," he said.

"I'll have him marked as a prisoner of risk noting that he was assaulted in the cells today."

Leclair was on bail for a raft of other charges including two counts of possessing an offensive weapon, common assault, and allowing a dog to attack or harass after an incident in February involving his victims.

Police allege Leclair punched his victim in the jaw while holding a rusty machete in the other hand and allowing his dog to "charge" towards his other victim after telling them he would "f--k you up tonight" as they walked past his house, according to the facts.

The matter will return to court in August.
