FFS she made the comment on Facebook in the UK, she was not in Dubai!
And I think referring to someone as a horse is not an arrestable offence in most countries!
What mentality does it take to actually take such offence that you go to the authorities!!
Do the Dubai authorities have nothing better to do than follow up on this sort of thing.
In the UK (and the rest of Europe) if you walked into a police station and said you wanted to lodge a complaint about someone who had called you a horse on Facebook in Dubai - you would laughed out of the place and told to stop wasting police time!!
The world has gone crazy!!
