Dairy robbers fractured the skull of a Hamilton shopkeeper with a machete. Two masked men entered the Emm Jay Dairy, on the corner of Brookfield and Grey Streets in Hamilton East, at 8.30am yesterday. The pair, armed with an axe and a machete, struck the lone worker on the head and hands with the blade. They took the entire till drawer and some cigarettes before fleeing in a stolen silver Mazda Familia, registration FEP218. The shopkeeper remains in Waikato Hospital.
