Seven people have been charged over riots in the Goldfields town of Kalgoorlie earlier in the week, following the death of 14-year-old Elijah Doughty the previous day.

Seven males aged from 15 to 25 have been charged after the riot outside the Kalgoorlie courthouse on Tuesday, where people were seeking to attend the hearing for a 55-year-old man charged with unlawfully killing the teenager.

Elijah was allegedly hit by a ute while riding on a motorbike in bushland off Clancy Street in Boulder.

A police taskforce has been formed to investigate the issues that led to the riots.

Police Minister Liza Harvey said she had heard allegations of a pattern of retribution in Kalgoorlie, where the owners of stolen dirt bikes had been hunting down the thieves.

"With respect to vigilante action, if you like, police are investigating the claims that that has become a part of the culture in Kalgoorlie, and that is certainly not something that we would encourage in any way shape or form," she said.

Mrs Harvey said police were going through social media sites and CCTV footage to see if appropriate charges can be laid against people who had acted violently.

Premier Colin Barnett said he planned to visit Kalgoorlie after what he described as a "very disturbing episode".

"It was a race riot, there's no doubt about that, tempers ran high and there's a number of country towns where that can happen but it hasn't happened for a long time," he said.

Attorney-General Michael Mischin, who is in Kalgoorlie, said he did not accept Tuesday's riot was a sign the justice system was failing the community.

"Where things seems to have gone awry is that a number of people have taken advantage of the emotion and the tensions occasioned by the death of this young teenager in order to exploit the situation, but that is not reflective as I understand it of the attitudes of the community".

Peaceful protest held in Perth

Extra police officers have been temporarily sent to Kalgoorlie to support existing staff, although the officers in charge at the station have told Mrs Harvey they have sufficient numbers long term.

Meanwhile, relatives of the Kalgoorlie teenager were among dozens of people, some wearing Black Lives Matter t-shirts, who attended at a peaceful protest in his memory at Perth's Forrest Chase.

"Elijah had a hard life. His mum will never get a chance to say goodbye to her son, it breaks our hearts," his aunt Donna Schultz told the crowd.

Elijah's cousin Preston Colbong called for solidarity.

"This isn't a black problem, or a white problem, this is a community problem that we need to fix together," he said.

"It's an opportunity for the leaders in our community, the leaders in our government, to take that forward step to say this is something that we can't allow to continue to happen.

"And it's about remembering a young man that we've lost. It's the same thing that we're going through every couple of weeks, every couple of months ... a young man who was lost in prison or a young woman who was run over."

Mingli Wanjurri McGlade led the meeting and said she was pleased to see so many people, both Indigenous and non-Indigenous.

"We don't want this to happen ever again," she said.

"We hope that this is a new beginning, unfortunately a young boy has lost his life, it's just so sad, but from here we hope people will realise we can't do this anymore."

Elders in Kalgoorlie have also urged calm while also calling for change to improve the outlook of young Aboriginal people.
