An 81-year-old is being hailed as a hero after intervening in a Samurai sword attack in Woolston.
A 61-year-old woman will undergo surgery for arm and hand injuries when she was allegedly attacked by a 40-year-old man in St John St at about 5.30am today.
Detective Senior Sergeant David Harvey said the 81-year-old neighbour was extremely brave.
"The actions of the neighbour prevented this incident from escalating," he said.
Detective Senior Sergeant Harvey said a man who was visiting the address was arrested at the scene on charges of assault, threatening to kill and resisting arrest.
No-one else is being sought in connection to the incident.
Police were today speaking to neighbours.
The man is to appear in the district court on Monday.
