Armed police and a dog were used to capture a man who doused himself with fuel and threatened to set himself alight after he allegedly assaulted another man north of Dargaville.
The man was later taken to Whangarei Hospital for treatment on two broken ribs, a punctured lung and dog bites sustained while he was arrested at Tutamoe, about 48km northwest of Dargaville, on Sunday
Whangarei/Kaipara police area commander Inspector Tracy Phillips said police were called to a property at Tutamoe about 5pm on Sunday after reports that a man had been assaulted.
Ms Phillips said a man suffered serious head injuries and when police arrived the man who allegedly assaulted him became aggressive and made threats.
As police approached the man he covered himself with fuel and threatened to set himself alight with a lighter he was carrying so the Armed Offenders Squad was called.
