Four men have been injured, while two critical, in a shooting outside a nightclub in the Australian city of Melbourne.
The incident at the Love Machine venue is not thought to be terror-related.
As per the Australian newspaper “The Age said” investigators are likely to examine links to a motorcycle gang.
Mass shootings in Australia are rare.
The country overhauled its gun laws after 35 people were shot dead in Port Arthur, Tasmania in 1996.
Last year, the country saw its worst incident since then after seven members of the same family died in a murder-suicide.
Police say two men, aged 29 and 50, and were hospitalized with non-life threatening injuries in the shooting at Love Machine.
One of those in a serious condition is aged 28, but no details about the fourth victim has been released.
