Comanchero bikie Axel Sidaros cleared of attempting to murder Peter Zdravkovic

Axel Sidaros shook his head, but gave his family a thumbs-up moments after learning on Wednesday afternoon that he would be staying behind bars.

The 26-year-old stood trial twice over a fiery June 2018 incident at the Calwell home of deposed Canberra Comanchero boss Peter Zdravkovic.

Home CCTV of the late night assault shows a group of disguised men shooting at a naked Zdravkovic, who had part of a finger blown off by bullet, and setting fire to three of the man's cars.

Sidaros, who was accused of being the intruder firing a shotgun, repeatedly denied any involvement.

He was last year found guilty by a jury of seven charges, including attempted murder, and subsequently sentenced to 14 years in jail.

But the sentence was quashed after he successfully appealed against his convictions and won a recent judge-alone retrial in the ACT Supreme Court.

On Wednesday, after nearly two weeks of deliberations, Justice David Mossop cleared Sidaros of the attempted murder charge.

However, the judge found the 26-year-old guilty of intentionally inflicting grievous bodily harm, arson, attempted arson, aggravated burglary, unlawfully discharging a firearm and riding in a stolen vehicle.

Justice Mossop provided lawyers for the defence and prosecution with written reasons explaining his verdicts, but made an order temporarily forbidding publication of the reasons.

It was the Crown's case during the retrial that Zdravkovic, after being booted out of the gang, offended the Comancheros by burning his gang colours and refusing demands to hand over motorcycles and other goods.

He was subsequently attacked by three unidentified men and Sidaros, who was a Comanchero nominee working towards full membership at the relevant time.

Sidaros, who has been in custody since his arrest, will be sentenced in February.
