A search is continuing for a man missing in bushland in the Canning Mills area, south-east of Perth.
Police say fears are held for the safety of Jason William Harding who has not been seen since December 28.
On Thursday, his vehicle and other personal belongings were found abandoned, prompting a search for the 49-year-old.
It continued on Friday with local police using horses and drones to comb the area.
"Given where the vehicle was located, and the hot weather experienced in recent days, concerns are held for Mr Harding's welfare," police said in a statement.
They are keen to speak with anyone who may have seen or spoken to the missing man since Monday.
