A man and a woman were arrested following an investigation into the movements of Dezi Freeman, who was shot dead this week.
Victoria Police arrested the pair at two properties in the state's northeast on Saturday morning but released them in the evening, pending further enquiries.
"Detectives from Taskforce Summit arrested two people this morning as part of their ongoing investigation into the movements of Desmond Freeman," a police spokeswoman said in a statement.
The police interviewed the pair but have not charged them. They are not Freeman's family members.
The 56-year-old fugitive was shot dead in a hail of bullets by specialist police on a remote property in Thologolong, near Walwa on the Victoria-NSW border, on Monday after a seven-month manhunt.
Freeman was wanted for the alleged fatal shooting of Neal Thompson and Vadim de Waart-Hottart, who were among a team of police officers serving a warrant at his Porepunkah home in late August.
Speculation has been rife over how Freeman came to be in Thologolong, which is about 150km from where he fatally shot the officers.
The property is owned by Rick Sutherland, but his brother Neil said he had no idea the fugitive was camped out there.
Neil said his brother had been in Tasmania at the time and, unlike Freeman, was not a sovereign citizen.
Sutherland, who lives two properties from the site of the shooting, has reportedly said his brother has contacted police to offer his assistance.
Investigators are exploring the possibility Freeman received help from others in evading police for 216 days, with police chief Mike Bush saying it would have been very difficult for him to get to where he was without assistance.
