DNA of senior bikie Aofangatuku Langi found on fuel container lid near scene of shooting, arson

More than two years on from the incident, The Canberra Times can now reveal police are still investigating the potential involvement of Aofangatuku Fatafehi Finau Langi, who is the bikie gang's local sergeant-at-arms.

CCTV of the June 2018 attack shows four hooded assailants sneaking onto the Calwell property of former chapter commander Peter Zdravkovic, who had left the Comancheros because of a bitter internal feud.

Two of the disguised figures can be seen shooting into Mr Zdravkovic's house, while the others pour fuel around the property and inside through a glass door.

The accelerant is eventually set alight and flames engulf three of Mr Zdravkovic's cars, which were parked in the backyard, as the offenders flee.

Mr Zdravkovic was shot in the hand during the incident and lost the top of one of his fingers.

To date, Axel Sidaros is the only person to have been charged with carrying out the attack. The 25-year-old, who was a Comanchero nominee at the time of the incident, was found guilty last year of seven charges including attempted murder and arson. He is now serving a 14-year jail sentence.

Police continue to investigate the incident, and documents tendered to the ACT Supreme Court last week reveal that officers suspect Mr Langi may have been one of the other three assailants.

"One of the males was seen on CCTV footage to be of large build, matching the appearance of [Mr Langi]," the documents say.

"This male was seen to take possession of a fuel container and empty the contents into the residence through the damaged glass sliding door.

"A fuel container lid of the same brand was located in front of Zdravkovic's parents' house (in the same street) which was also shot at by the offenders as they departed Zdravkovic's residence.

"[Mr Langi's] DNA was located on the fuel container lid and investigations into his involvement are still ongoing."

Mr Langi has been behind bars on remand at the Alexander Maconochie Centre since February.

The 31-year-old is awaiting trial, having pleaded not guilty to nine charges laid following an incident in November last year.

He is accused alongside Christopher Millington of carrying out a home invasion and shooting at then-Nomads member Alexander Victor Miller before setting fire to the Kambah house where Mr Miller was living.

The police documents tendered in court reveal Mr Langi is also suspected in a raft of other incidents, some of which are still under investigation.

The incidents include the "point blank" shooting of a Nomads member who received gunshot wounds to the legs in a September 2017 incident at his home.

The documents also name Mr Langi as a suspect in:

Mr Langi last week failed in a fresh application for bail on the charges relating to Mr Miller.

The refusal of bail came after police and prosecutors expressed fears that if Mr Langi was released, he would orchestrate reprisal attacks against whoever the Canberra Comancheros believed to be responsible for the fatal stabbing of chapter commander Pitasoni Ulavalu in Civic earlier this month.

Crown prosecutor Anthony Williamson told the ACT Supreme Court last week that as sergeant-at-arms, Mr Langi was responsible for coordinating violence and retribution against those who threatened the gang.

Police are yet to arrest or charge anyone with involvement in the death of Mr Ulavalu.

Mr Langi has long held positions in Canberra outlaw motorcycle gangs, according to court documents, which say his association dates back to a 2012 affiliation with the Rebels.

Police believe that as the second-in-charge of the Canberra Comancheros, he is likely to succeed the late Mr Ulavalu as chapter commander.
