Human remains found at a house in Launceston may be those of a man who has been missing for nearly 10 months, Tasmanian police say.
Tyson Timothy Clark-Robertson, 24, was last seen leaving a Newnham supermarket in July but was only reported missing last month.
Forensic officers discovered remains during a property search in Mitchell Street in Mayfield on Tuesday night.
A 45-year-old man, a 53-year-old man and a 19-year-old woman are in custody and assisting police with their enquiries.
Police believe Mr Clark-Robertson may have met with foul play.
