if someone is laying hands on your child, that's assault if you think about...they gave him a bloody nose and caused him harm. Most schools should have a 0 tolerance policy. If not, I'd see the principal and bring the brat in who harmed your son. If the bully doesn't stop, heck I'd file assault charges on this kid and get a restraining order if the district doesn't do anything.
Nobody should be laying a hand on your child. NOBODY.
