A dark grey or black hatchback was sighted by police driving erratically and at significant speed in the southbound lanes of the Tuggeranong Parkway heading towards Kambah on Thursday night.

Police say they didn’t pursue it due to the risk posed to other road users, but now they’re seeking community help to identify the vehicle and driver.

Anyone with dashcam footage of the dark hatchback on the Tuggeranong Parkway at around 9.15pm should call 1800 333000, or via the Crime Stoppers ACT website.
