The Northern Territory Police Force continue to hold concerns for the welfare of 31-year-old Marius who has been missing in East Arnhem Land for a week.

The search has involved NTPF Search and Rescue members, local Police, NTES, NTFRS, Dhimurru Rangers, Yirralka Rangers, NORFORCE and Nautilus Helicopters, as well as drone-in-a-box systems which have been remotely piloted from Darwin.

While police have not yet found any evidence that indicates the whereabouts of Marius, the search is persistent and four helicopters are in the air today scanning an area of about 1500sqm.

Police are particularly interested in anyone who saw the vehicle Marius was believed to be driving in on the day of his disappearance.

The vehicle was a Blue Toyota Hilux Dual Cab with the registration CG10EZ.

The vehicle has since been recovered abandoned on the Central Arnhem Highway.
