(2) A commitment under this section may be varied or, in the case of a young person who proves to be of so unruly a character that he cannot be safely detained in such custody or who proves to be of so depraved a character that he is not a fit person to be so detained, revoked by any court acting in or for the place in or for which the court which made the order acted, and if it is revoked the young person may be committed to prison.
