A woman is dead after an Anzac Day double shooting in Invercargill.
A second victim wounded by gunfire last night is in hospital with serious injuries.
Police said a person was now in custody and helping with the investigation. They were not looking for anyone else.
The fatal shooting happened just after 8pm on Otepuni Ave in the suburb of Newfield.
A witness described seeing a man pull up on a bike, put on a balaclava and pull something out from his jacket shortly before the shooting.
