ACT Policing released the footage on Friday with a call for community assistance to help identify the offenders.

The footage shows three men – two armed with a handgun and shotgun – scaling the rear fence of the Calwell home of a rival gang member about 10.45pm on June 28.

The men open a roller door, allowing a fourth man to enter, before pouring petrol on three vehicles.

A firefight then breaks out when the armed men spot the rival - former Comanchero ACT president Peter Zdravkovic - inside the home.

Police allege Mr Zdravkovic armed himself with a rifle and returned fire, but was wounded – later losing a finger – in the ensuing shootout.

Police said an innocent neighbour was almost injured when a stray bullet passed through an exterior wall and into an adjacent home, just missing a sleeping resident.

The attackers flee in a stolen vehicle after setting three cars ablaze - one attacker's shoes catch fire during his escape - but stop down the right to pump three bullets into a second house linked to the target.

Police have charged two men in relation to the incident, but hope the public can help identify the others involved.

Canberra Comanchero Axel Sidaros, 24, has pleaded not guilty in the ACT Magistrates Court to attempted murder over the incident.

Police allege Mr Sidaros is the attacker armed with the Adler lever-action shotgun.

The alleged target, former Comanchero ACT president, Peter Zdravkovic, 36, has pleaded not guilty to firearm and drug charges.

Police allege the shootout is part of an internal Comanchero Outlaw Motorcycle Gang war.

Police say the Canberra chapter of the gang split into two blocs earlier this year, with a faction loyal to Mr Zdravkovic then cutting ties with the Comanchero and patching over to the Finks.

However, Mr Zdravkovic denies he is a Fink.

The split sparked tit-for-tat violence between the warring groups, including a number of shootings, arsons, and a daytime public brawl in July.

Detective Superintendent Scott Moller said the Calwell footage was "absolutely shocking", and said he would like to tell the offenders that police would not stop until they were all before the courts.

"[It is] outrageous to think that in our capital city, this type of criminal behaviour is ongoing, but certainly, it's here and it's real," Detective Superintendent Moller said.

"From an ACT Policing perspective, this is our highest priority and we are committing all of our available resources to solving this crime."

Detective Superintendent Moller said the risk bikie-related violence posed to innocent people was unacceptable.

"To have multiple shots discharged in this incident and to have one bullet narrowly miss an innocent person only highlights the grave risk these offenders pose to our community," Superintendent Moller said.

"We are urging anyone with information relating to this incident, or who may be able to identify the offenders to come forward."

Police are urging anyone who may have any information that could assist police to contact Crime Stoppers on 1800 333 000, or via the Crime Stoppers ACT website.
