Canberra: At least four people have been shot dead by a gunman in Darwin, northern Australia, police say.
Eyewitnesses said the gunman entered a motel in an inner suburb of the city and opened fire in a number of rooms before fleeing.
Police responded at about 18:00 local time (08:30 GMT) and arrested the man an hour later.
Australian Prime Minister Scott Morrison said the shooting was not terror-related. Police said they believed the man had acted alone and they were not looking for any other suspects.
Mass shootings in Australia have been a rare occurrence since the country overhauled its gun laws in 1996, in the wake of a shooting in Tasmania that killed 35 people.
