Solomone, 15, died after being fatally stabbed in the chest during a fight near the Brimbank Shopping Centre, near Deer Park in Melbourne's west, last Tuesday night.
ABC News reports six boys between the ages of 13 and 16 have been charged with violent disorder and affray, but no one has yet been charged with his murder.
On Tuesday, one of the boys accused of participating in the attack faced a children's court and was granted bail, which police and prosecutors did not oppose.
