Police are seeking the driver of a BMW and asking for information from the Ceduna community following a pursuit with the vehicle on Saturday morning.
At about 1.30am a police patrol noticed a black BMW speeding on Smith Street at Ceduna without its headlights on.
In the next 40 minutes the same vehicle was twice spotted driving erratically on Kerley Street and Denial Bay Road heading back towards Ceduna.
Police attempted to pursue the car, but it failed to stop and the pursuit was halted.
Just before 2.30am a patrol again spotted the BMW on Thevenard Road driving dangerously with no lights and on the wrong side of the road.
The patrol was forced to swerve to avoid a collision and stopped, while the BMW then did a U-turn and drove directly at the stationery police vehicle before swerving at the last second.
The black BMW 318i was last seen travelling west on Eyre Highway past the quarantine station.
Following a search the vehicle was found abandoned a few hours later, about two kilometres from Ceduna, where it was impounded for forensic testing.
Police are searching for the driver and ask anybody with information on the identity of the person, including dashcam vision of the BMW, to contact Crime Stoppers on 1800 333 000.
