When a child is brought to a detention facility pursuant to section 724(b)(iii) of the Family Court Act, the administrator responsible for operating the detention facility is authorized, before the filing of a petition, to release the child to the custody of a parent or other relative, guardian or legal custodian when the events that occasioned the taking into custody appear to involve a petition to determine whether the child is a person in need of supervision rather than a petition to determine whether the child is a juvenile delinquent.
