Neither the fact that a person was before the family court under this article for a hearing nor any confession, admission or statement made by him to the court or to any officer thereof in any stage of the proceeding is admissible as evidence against him or his interests in any other court. Another court, in imposing sentence upon an adult after conviction, may receive and consider the records and information on file with the family court concerning such person when he was a child.
