The lawyer for one of Canberra's most-notorious career criminals says his client could be rendered "extremely vulnerable" in jail by members of the Satudarah bikie gang.
Prosecutors allege Matthew James Massey, 44, went into a Flynn house last September and stabbed Steven Ceissman in his sleep.
They allege after Mr Ceissman woke up, Massey threatened to stab another resident, too.
The career criminal has flat out denied the allegations, and in October questioned why he'd go into the house "like an idiot without a balaclava" and wearing footy shorts.
He has pleaded not guilty to aggravated burglary, theft and intentionally wounding Mr Ceissman.
Prosecutors have said Mr Ceissman and his family fear Massey will come after them if he is released on bail, but lawyer Paul Edmonds on Thursday said that was "absurd".
He said Mr Ceissman was the sergeant-at-arms of the ACT's Satudarah bikie gang chapter as at October last year.
"It's frankly laughable that the strongman or enforcer of an outlaw motorcycle gang is claiming to anyone [if he is] ... that he cannot protect himself," Mr Edmonds said.
The lawyer said gang members in the Alexander Maconochie Centre could corner Massey and attack him, and "within a confined space, [he] is extremely vulnerable".
But prosecutors said that, although Mr Ceissman had been a member of Satudarah before he left last October, he had never been sergeant-at-arms of the gang.
They said there was no risk to Massey in jail and in fact, the 44-year-old had chased his cellmate Darin Keir around a prison wing and threatened to "pump him". Keir is the president of Canberra's Satudarah chapter.

In 2014, an alleged thief cited concerns for his safety if locked up with Massey as a special or exceptional circumstance during a bail hearing in the ACT Magistrates Court.
But Magistrate Karen Fryer rejected the application and remarked: "Quite frankly, if Mr Massey was the reason for not putting anyone in custody, we'd only have Mr Massey in custody."
The prosecutors on Thursday said Keir had made a phone call urging someone to convince Mr Ceissman to retract his statement, which was a key piece of evidence.
They rattled off a long list of convictions from Massey's criminal record in an attempt to further justify why he shouldn't be granted bail.
The convictions included three armed robberies, nine burglaries, five assaults, six counts of obstructing a territory official, counts of kidnapping and forcible confinement, and offences for escaping police custody.
Mr Edmonds argued Magistrate James Stewart should grant Massey bail, and said he should consider that the serial criminal may be "slowing down" with age.
Massey has already been refused bail twice over the alleged Flynn incident, but Thursday was the first time he was represented by a lawyer.
The magistrate said he needed more time to consider whether Massey should be granted bail.
He adjourned the application until next Friday, and said prosecutors should use the time to come up with documented proof there was a warrant out for Massey in NSW.
