On March 12 at 2.25pm, officers were patrolling Tuggeranong Parkway in an unmarked car when they were overtaken by a blue Ford Falcon utility.

Police followed the ute to determine its speed and safely intercept it. Officers allege the ute reached speeds estimated at over 150km/h.

Police stopped the vehicle and gave the driver a roadside breath test, which returned a positive result.

The officers took the driver to the City Police Station for further analysis, returning a result of 0.227, which is more than four times the legal limit for a full licence holder.

The man has been granted bail and will be summonsed to appear before the ACT Magistrates Court at a later date charged with level four drink-driving, aggravated dangerous driving and speeding.

Police are seeking witnesses to a serious assault in Palmerston on Friday night.

About 10.15pm on March 15, ACT Policing received a call to Tamborine Close. At the scene, three victims, one with critical injuries, were taken to hospital. A man was also arrested and later transported to hospital.

Police would like to speak with anyone who saw (or has CCTV footage) of a man in Tamborine Close and surrounds prior to 10.15pm. He is described as Caucasian, thin build, late teens or early 20s with dark hair. He was wearing dark-coloured track pants with no shirt or shoes.
