The 22-year-old Hamilton woman who was attacked by two clowns in the early hours of Saturday morning fled to a neighbouring house to raise the alarm.
The woman suffered moderate injuries during the terrifying incident and police are still hunting for her clown attackers.
The assault comes amid a social media frenzy with people posting sightings and videos of scary clowns online across the country.
The sightings have been called the "scary clown epidemic" and originated in the US, where ghoulish clowns have tried luring children into forests.
