A search on Thursday focussed on an area of the Darebin Creek Reserve near Seddon Reserve in Melbourne's north east, and detectives want to speak to anyone who saw suspicious activity in the area on 1 or 2 February.
Investigators are also asking residents of Epping, Doncaster and Ivanhoe West to check their CCTV footage and dashcams.
They are looking for footage of a black 2008 Mazda CX9 station wagon, with registration WKE 850, or a white Toyota Land Cruiser.
Mr Tan, from Doncaster, was initially arrested on Sunday after allegedly trying to avoid police for several days but was released without charge.
