ACT Policing is seeking witnesses to a road rage incident on the Tuggeranong Parkway earlier this week.

About 8.30am on Monday morning, 20 November, a grey Nissan X-Trail and a white Holden Commodore were travelling northbound on the Tuggeranong Parkway near the Glenloch Interchange.

A short time later, the Commodore has caused the X-Trail to stop in the left-hand lane of the roadway, at which time the driver of the Commodore exited his vehicle and allegedly caused damage to the X-Trail.

The Commodore was seen allegedly driving in an erratic matter, swerving in and out of lanes, prior to the incident with the X-Trail.

Police would like to speak to anyone who witnessed the incident, the lead up to the incident, or anyone who may have dash-cam footage of the incident.

Anyone with information who can assist police is urged to contact Crime Stoppers on 1800 333 000, or via the Crime Stoppers ACT website.  Please quote reference number 7598943. Information can be provided anonymously.
