The two men arrested as part of an ongoing police probe into the movements of Dezi Freeman have been released from custody, pending further inquiries.

Freeman was shot dead at a remote property in Thologolong, near the Victorian-NSW border on March 30.

He had been on the run for seven months after fatally shooting two police officers who were visiting his home in Porepunkah in Victoria's north-east last August to serve an arrest warrant.

After Freeman was shot dead, police launched an investigation into those who may have helped Freeman evade authorities for months.

On Tuesday, a 48-year-old man and a 45-year-old man were arrested at two separate locations in north-east Victoria. 

However, 24 hours later, police confirmed they had been released.

'Two men aged 48 and 45 arrested by Taskforce Summit yesterday have been released pending further enquiries,' a statement read.

'The investigation remains ongoing and as such, we are not in a position to provide further details at this immediate time.'

It comes weeks after a man and woman were arrested at separate properties on April 4 in relation to the ongoing investigation into Freeman. 

The pair were later released without any charges brought.

The latest update comes two days after a coronial inquest into the deadly police operation at Porepunkah last August began in Melbourne.

Officers had attended the property to execute a search warrant and speak to Freeman over alleged child sex offences when he shot dead Senior Constable Vadim De Waart-Hottart and Detective Leading Senior Constable Neil Thompson.

A third officer was shot in the leg but survived.

State Coroner Judge Liberty Sanger opened an inquest on Monday by paying tribute to the fallen officers.

The inquest heard that Freeman had mocked Sen Const De Waart-Hottart and looted his body after shooting him in the head with a shotgun.

'F***ing scum ... you f***ing die in f***ing hell,' Freeman shouted as Senior Constable De Waart-Hottart lay on the ground.

Standing over the bodies of his victims, the gunman unleashed his hate-filled rant at the dying officers.

'I had no choice. I had no choice,' Freeman said repeatedly after shooting the officers.

A separate inquest is examining Freeman's final moments.

It was revealed on Tuesday that specialist police continue to work without body-worn cameras, eight years after Victoria Police began rolling out the technology.

None of the officers who shot and killed Freeman were wearing body-worn cameras.

The officers were members of Victoria Police's special operations group, who conducted covert surveillance on the fugitive's location for a week before moving in and attempting negotiations with him for several hours.
