Can someone give me a simple answer, or link to an authoritative source for the answer. If a serviceman is a suspect in a civilian criminal case, at what point is it a requirement to inform the Chain of Command? For the puposes of this discussion, an alleged incident, in the UK, by a UK based serviceman, off duty, not on military property and not involving military property or other military personnel. In other words, no military involvement. The individual was interviewed under caution and let go but told that he might be charged with an offence. Is it a requirement, as I suspect, to notify the Chain of Command at the point a formal charge is made (assuming that it goes that far)? Once an incident is formally reported to the Chain of Command, what procedures should be followed. I am a little rusty on this subject and need to bring myself up to speed. Serious replies please, by PM if you prefer.
