Police are hunting a man who approached a young girl with a hammer at a Waikato school.
He reportedly jumped a fence at Te Pahu School, a rural school about 30km south east of Hamilton yesterday.
Senior Sergeant Robbie Hermann told Fairfax the school went in to lockdown about midday.
He was described as bald with a goatee, "scruffy looking" and aged in his 30s-40s.
He was driving a silver car.
