A man wanted over a suspected murder in northern Tasmania has been arrested by police after spending the best part of a day on the run.
The 47-year-old, who was found with a large knife, was taken into custody in the Parkham region around 4pm on Wednesday.
He was the subject of an extensive bushland manhunt following the suspicious death of a 69-year-old man at his home at Reedy Marsh on Tuesday night.
"This has been a challenging situation and I'd like to thank the community for their support," acting commander Stuart Wilkinson said.
"I'd also like to thank the police who attended and brought about a safe resolution to the matter.
"Our sincere condolences go to the family of the man who died in the most tragic circumstances."
The man's death is being treated as a murder by police but no charges have been laid.
His 60-year-old wife suffered cuts in the incident and was taken to hospital, but has since been released.
Two men, aged 39 and 44, and a 28-year-old woman were initially taken into custody but have been released without charge.
Specialist police, a rescue helicopter and drones were used in the search for the man.
