A man who allegedly assaulted an essential healthcare worker at a COVID-19 testing site in Sydney’s north-west has been charged.

A female staff member was working at a Dundas COVID-19 testing site when she was approached by an unknown man who was not wearing a mask.

Police have been told the man began filming the 31-year-old worker on his mobile phone, before verbally abusing her about vaccinations.

The man then allegedly dislodged the woman’s mask and punched her to the head.

The man fled the scene on foot while the woman was treated at the scene.

Following inquiries and the release of CCTV, a 50-year-old man was arrested in Telopea this morning.

He was taken to Granville Police Station, where he was charged with common assault, two counts of prohibited drug possession, and breach of the public health orders.
