In a proceeding alleging a youth to be a delinquent youth:
(1) an extrajudicial statement that would be constitutionally inadmissible in a criminal matter may not be received in evidence;
(2) evidence illegally seized or obtained may not be received in evidence to establish the allegations of a petition against a youth; and
(3) an extrajudicial admission or confession made by the youth out of court is insufficient to support a finding that the youth committed the acts alleged in the petition unless it is corroborated by other evidence.
