You can't start it yourself. You have no legal standing in this whatsoever. This is not your problem, it is none of your business. Period.
The boy cannot file a statement on his own. He must do this with his parents or legal guardians. You cannot accompany them. If he/they don't want to do this, that is their legal prerogative.
Again, you have no involvement in this. If you go to the police with this, the police will say something along the lines of "butt out buddy" to you. You might also get sued by the boy's parents/legal guardians for interfering and publicizing their private business. And they would probably win.
