Detective Sergeant Jason von Tunk, of the Portland crime investigation unit, said the vehicle was seen on the Portland-Nelson Road, at Gorae West, heading towards Nelson at 7pm.

The sedan was found on a dirt track in a pine plantation on the Portland-Nelson Road at Kenbruck mid afternoon Sunday completely burnt out.

The Ford was worth about $2000.

The dirt track was about three kilometres east of the Winnap intersection.

"The vehicle was involved in an evade police incident on Friday evening with Portland police officers," he said.

"There were no number plates on the vehicle, it was not registered and had previously been sold, but is still in the previous owner's name."

Detective Sergeant von Tunk said police wanted to identify who had been driving around in the vehicle.

He said it was seen at a BP service station on Portland's Madeira Packet Road just before evading police.

"It was also seen in Thorns Road on Saturday in west Portland," he said.

Anyone with information is requested to contact the Portland police station or Crime Stoppers on 1800 333 000.
