A woman did everything right to thwart an attack by a man as she walked home in Hamilton early on Saturday morning, police say.
The 24-year-old student was walking along Boundary Rd about 2am when she became suspicious of a man following her.
"As she was walking along the cobbled footpath from Victoria St to Boundary Rd towards the Whitiora Bridge the woman was looking at Facebook on her phone which she then used to ring 111," Constable Lucy Southall said.
"While still on the footpath the woman turned around to find a man standing behind her who grabbed her mouth and punched her as she tried to fight off his attack."
The woman fell to the ground and the attacker threatened to kill her as she tried to recover her phone.
