The South Australian Police Commissioner, Mal Hyde, says tougher penalties are needed to deal with the so-called gang of 49 that is being blamed for more than 700 violent crimes over the past few years.
The group has also been linked to a high-speed chase this week, resulting in an accident that killed an innocent man.
A special task force, named Operation Mandrake, has been looking into the activities of the group, which is made up predominantly of Aboriginal youths.
Relatives of a 15-year-old boy suspected of being involved say the group have brought shame upon their families.
The boy's aunt has told the ABC's Stateline program that she does not think the group is an organised gang.
But his mother says the current system of putting underage offenders into juvenile detention centres is not working.
"They go into McNally's and they come out [and] they still re-offend, so McNally's ain't helping them," she said.
"They should get the re-offenders and take them to bush."
She says she feels powerless to control her son.
"It's alcohol and drugs, the young boys are into that, they'll steal for that pleasure as well," she said.
"If there's been ram-raids on liquor stores or whatever, they'll consume the alcohol, they won't sell it."
Commissioner Hyde says most of the gang members are a lost cause.
"We're trying to rehabilitate one person and the cost of doing that is many victims, destroying their lives," he said.
"So when people like that young boy and others that he was talking about show an indication that they'll continue to offend we need to protect the community and if that means keeping them inside, then that's what needs to be done."
