Matamata robberies
Waikato police said they arrested a 19-year-old man after aggravated robberies on two separate dates at one commercial premises in Matamata's Tower Road.
On Tuesday 26 March and on Thursday 4 April, the man "threatened employees with a knife, and targeted tobacco, cigarettes, and cash", a police spokesperson said in a statement.
After the second incident, the man tried to get away on a bicycle, which was found not far from the scene.
A police dog team then tracked the scent to a nearby property. Police were then able to locate items that had been stolen and to arrest the man.
He faces multiple charges, including aggravated robbery and burglary, in relation to the two Matamata robberies, and appeared in Hamilton District Court on Friday 5 April. He was remanded to appear on 22 April.
"We understand how distressing incidents like these can be for victims and we hope arrests like this can provide reassurance to both the victims and the community," Waikato East Detective Sergeant Ben Norman said.
