Port Stephens-Hunter police are seeking the public's help to locate a man who reportedly spat on a Maitland COVID testing clinic worker.
Police made the appeal on Monday over the incident, which occurred about 3pm on Saturday.
It comes amid huge demand at clinics across the region and with six new cases in the region on Monday morning.
Police said an unknown man was waiting for a drive-through test at Blomfield Street in Maitland when he was told the clinic was closing.
The man became abusive and it is alleged he "spat at the employee, narrowly missing him, before fleeing in a white-coloured vehicle towards Wallace Street".
Police said a man described as being of caucasian appearance and without his two front teeth may be of assistance with their inquiries.
Police ask that any witnesses or anyone with dash-cam footage call Maitland Police Station on (02) 4934 0200.
