In really can't imagine any scenario onboard a legacy European carrier, where a male passenger has been masturbating next to a female ditto, who reports same to the crew, and the crew does nothing about it. Sorry, it just doesn't wash.
What we have here is an entitled brat who didn't get an upgrade she felt entitled to. She then runs off to daddy, who's a big shot in a deeply corrupt tin-pot dictatorship masquerading as a democracy, and daddy does what a mafia Don would do: go after whomever offended his little girl. Luckily for him, being a big shot in what is misleading called a legal system, he can have the offenders locked up and 'prosecuted', knowing full well there'll be no consequences for him and his family.
BS, I say. BS.
