"Daylight sex attack at campus"
A 20-year-old woman was confronted by a man aged in his 20s at the maths and sciences block about 8.30am, before being punched and dragged into a secluded area of the university grounds, Hamilton police said.
The woman screamed and "vigorously resisted" the man throughout the attack and eventually managed to flee her attacker, police said.
The offender was described as dark skinned male about 160-170cm tall and of medium build.
He had shoulder length black hair off his face and was wearing dark trousers and shoes, and a white long-sleeve sweat top with two distinctive black lines down the full length of the sleeves.
