I was hoping this was in some way related to legislation against the “troubled teen industry” but the real cause is that there was a violation of a restraining order:

Gaviola’s son […] obtained a domestic violence protection order against his mother. […] that order was violated when two employees of Sandoval’s agency, a transportation company that delivered minors to the boarding school, picked him up at a skating rink in Fresno.

He was held in handcuffs for more than 24 hours while he was driven to Missouri

Yeah put that bitch away.
