Two men have been released without charge by police probing Dezi Freeman's movements in the lead-up to the cop killer's final shootout.
Freeman triggered one of Australia's largest manhunts after he killed Senior Constable Vadim de Waart-Hottart and Detective Leading Senior Constable Neal Thompson at his home at Porepunkah, in Victoria's high country, in August.
The 56-year-old fled the scene and evaded capture until he was traced to a remote property about 150km away at Thologolong, near the Victoria-NSW border, in March, when he was shot and killed by police.
Task force detectives arrested two men, aged 48 and 45, at separate locations in northeast Victoria on Tuesday as part of an ongoing investigation into Freeman's movements after the police killings.
