Four killed in Darwin shooting rampage

Four men have been killed and a woman injured after a man allegedly opened fire in Darwin on Tuesday night.

The man, who was on parole and wearing an electronic monitoring bracelet, allegedly began shooting at people with a shotgun in central Darwin and was at large for roughly an hour before police arrested him at 6:45pm (NZT 9:15pm).

The alleged shooter was described by Northern Territory police as a 45-year-old caucasian man, wearing high-vis workwear. The Guardian reports that he is a suspected member of a motorcycle gang.

He was well-known to police and was released on parole in January.

Darwin locations now turned into active crime scenes include the Buff Club, Gardens Hill Crescent, the Peter McAulay Centre and the Palms Motel.

"Unfortunately, and sadly, four people have lost their lives this evening, this afternoon," said police commissioner Reece Kershaw.

"We're still trying to establish the intent and the motivation behind this."

The man was arrested at a local park after calling the police and asking to be put into protective custody.

Australian Prime Minister Scott Morrison tweeted that it was a "terrible act of violence", but it was not believed the shooting was an act of terrorism.

"My thoughts are with Territorians and the tight-knit community in Darwin."

The injured woman is now in hospital with a leg wound.
