What concerns me the most is the FO leaving the cockpit unattended, this under any civilized airline would result in an instant dismissal and regulatory (if not criminal) action. Coupled with the alleged assault this clown should not be let anywhere near a public transport airplane ever again.
But given the country in question (and depending on his connections) I suspect little if nothing will be done.
I suppose its one step better than the two flight attendants left in charge of a Jet A320 for at least 40 minutes whilst the crew snoozed back in first class.
