When there is a grand jury or other pending investigation of any criminal matter, a lawyer
participating in the investigation shall refrain from making any extrajudicial statement, for
dissemination by any means of public communication, that goes beyond the public record or that
is not necessary to inform the public that the investigation is under way, to describe the general
scope of the investigation, to obtain assistance in the apprehension of a suspect, or to warn the
public of any dangers, or otherwise to aid in the investigation.
