A man is assisting police after a healthcare worker was allegedly assaulted this week while working at a COVID-19 testing site in Sydney's north-west.
Police were told a man began filming the 31-year-old woman on his phone at the Kissing Point Road site in Dundas at about 4pm on Monday, before allegedly verbally abusing her about vaccinations.
The man, who was not wearing a mask, allegedly took off the woman's mask and punched her in the head.
Several people waiting for COVID-19 tests came to the woman's aid and her alleged attacker left the area.
The worker was treated at the scene and did not require hospital treatment.
NSW Police Deputy Commissioner Gary Worboys said information from the public has assisted officers since the "totally unacceptable" incident.
"Pleasingly, as a result of information that has been received, there is man right at this moment at his local police station assisting police with the inquiries," Deputy Commissioner Worboys said at today's daily COVID-19 briefing.
"Police will allege a man came up to one of the workers going about her tasks, pushed a telephone into her face, dislodged her mask, then struck her in the face, said some horrible things, and then left the scene."
Health Services Union NSW secretary Gerard Hayes said assaults on people working on the frontline of the pandemic "is beneath contempt".
"Health and hospital workers are already battling anxiety and exhaustion," Mr Hayes said.
"Violent attacks like this push them beyond breaking point."
Police are appealing for anyone who witnessed the alleged assault to call Cumberland Police (02) 9897 4199 or Crime Stoppers on 1800 333 000.
