Shocking footage has emerged of a wild bikie gunfight and arson in suburban south Canberra. 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.
