An 18-year-old man is in critical condition with self-inflicted knife wounds and an elderly woman was assaulted during a domestic incident in Hastings this morning.
Police said emergency services were called to a house just after 7.30am after a man was seen standing naked in the street.
Officers later found the man on the floor of the house with stab wounds to his chest.
Police said an elderly female relative of the man is believed to have been assaulted by the man. She was taken to Hawke's Bay Hospital with moderate head injuries.
Police are not seeking anyone else in relation to the incident.
