I think we should stop assuming that any illegal act automatically equals arrest. Four things to remember: arrest does not mean conviction. Two: even for an arrest to happen, you need probable cause- usually some kind of physical evidence, which might not be available. If the police know they can't prove anything, they'll let it be and keep an eye on the suspect. Three: the police usually deal with teenage suspects more leniently to avoid giving them a criminal record that will only lead to them committing more crimes in the future.

Four, most importantly: The school does not want bad publicity and is more likely to want to deal with incidents in-house. Unless it was something catastrophic (like committing arson and causing enough damage to put an entire classroom or floor out of commission) the school won't report the culprit, but discipline them to prevent it happening again. It's not just the police trying to improve their reputation after '89, remember.
