The nightclub shooter in Melbourne may have been evicted earlier because of bad behavior earlier due to revelations.
The police are investigating whether a stubborn group that has been removed from the Love Machine nightclub may be responsible for Sunday's deadly attack.
Archers in a stolen Porsche arrived at the location, in Prahran, on Sunday morning at about 3:10 am, firing four shots at the club.
Bouncer Aaron Khalid Osmani was shot in the head when he later died in the hospital, while patron Richard Arow (28) fights for his life in the hospital.

Commissioner for crime commander Tess Walsh confirmed that illegal motorcycle gangs and gangs are being investigated in the Middle East.
The police believe that experienced criminals are involved because of the nature of the attack, she added.
"It is clear that tensions escalate … this is a targeted attack, but we do not understand the motive or people involved," said Ms. Walsh.
The security staff at the site had been warned in recent weeks that tensions escalated between customers who were denied access or removed from the premises.

A source told the Herald Sun that recent renovations have attracted a new audience to the venue, which is now often full of & # 39; cyclists and strippers & # 39 ;.
Mid-March, a man who was removed from the shadow box location on the dance floor became physically violent with a street manager.
The police were forced to step in and keep him under control. He was subsequently refused entry again the following week.
Just two weeks ago, an incident involving up to 20 men also caught the attention of the police.
Security recognized a number of & # 39; people of value & # 39; in the group and they were all denied access.
Mr. Arow was outside the Love Machine nightclub (located the crime scene) in Prahran around 3:10 am on Sunday when four shots were fired at a stolen Porsche
& # 39; We think this is a fairly specific targeted attack, but we do not understand the motive nor the people involved with it right now & # 39 ;, said Mrs. Walsh.
She said the Love Machine owners were very cooperative and detectives hoped to be able to judge CCTV from the location.
They would also investigate whether it was linked to other recent underworld-related shootings.
Mrs. Walsh asked everyone with information to contact the police, especially those who were known to the shooters.
Ali Shohani, 26, was in the Love Machine nightclub when he saw the shooter open in the burning drive-by-shooting fire.
& # 39; He was shot just before me. Aaron looked at me straight in the face before he fell to the floor, & Mr Shohani told 9News as he smothered the tears.
& # 39; It was like a war zone, I have never experienced this in my life & # 39 ;, he said about the shooting in Prahran, which took place while standing in line to get to the nightclub.
Shohani fell to the ground after being shot.
& # 39; I thought they would continue shooting, so I just thought I should stay on the ground, & # 39; he said.
After being treated by paramedics on the spot, Shohani drove to the hospital where he underwent surgery to remove a bullet in his arm.
Social media messages from the 28-year-old friends and girlfriend of Richard Arow on Monday afternoon suggested that he had died.
Mrs. Walsh, however, confirmed that he was still alive hours later, but in a critical condition.
& # 39; Innocent people were affected in the most serious way & # 39 ;, she said with reference to Mr. Arow.

The friend Anthony Morello of the Chelsea FC fan wrote on social media: & # 39; Our friend was innocently in the wrong place at the wrong time.
& # 39; Your million-dollar smile and warm energy was so contagious and would illuminate any room you encountered.
& # 39; One of the nicest and most cheerful guys I have met … You will be missed by many and will be remembered forever as someone with a big beautiful heart. & # 39;
Another friend, Pasha Okanlar, accused himself that Mr. Arow was shot because he did not go out with him that night, as he often was.
Worried friends of Mr. Arow (pictured left with friends at another nightclub) reported about him on social media Monday afternoon
& # 39; My heart is broken, brother, you were something different, like you were a real brother, a real brother, always kept it real and saved it for one hundred percent & he said.
& # 39; So many tears laughed that we had my brother, we always had each other's backs but on this one time I was not there, look what happened. & # 39;
A third friend, Krystal Jade, wrote: & Your presence was of pure calm and positivity. You really were a respected soul full of kindness at every encounter. & # 39;
