UPDATE: A 74-year-old man was also arrested near Holyroodhouse in connection with a breach of the peace - he has also now been charged and is due to appear before Edinburgh Sheriff Court.

And now this:

@darshnasoni @Feargal_Sharkey @PoliceScotland A few years ago that would have been Liz Truss:

@darshnasoni @PoliceScotland Green hair. Throw the book at her.

@darshnasoni @wikileaks @PoliceScotland Green hair and tattoos. Another lost soul

@darshnasoni @AndrewW66619812 @PoliceScotland Section 5 of the public over act. Catch all law that technically prevents any kind of protest

@darshnasoni @PoliceScotland For all those in this thread saying that the woman in Edinburgh was arrested because of the swear word on her placard, explain this 👇 #NotMyKing

@darshnasoni @PoliceScotland if its the use of profanity, thats been on the books for a while now and used a lot

@darshnasoni @PoliceScotland @serpentza what do they call this in #China , something about "social harmony"?

@darshnasoni @Sionedwards @PoliceScotland I think the placards are valid protests and appear quite peaceful.

@darshnasoni @PoliceScotland Do the people in the UK have freedom of speech or the right to protest, looking at this it doesn't seem so.

@darshnasoni @PoliceScotland Brits need first amendment rights!

@darshnasoni @PoliceScotland i thought its free speech? this is North Korea

@darshnasoni @PoliceScotland Amazing how many people think it is fine to have the government tell them what the can and can’t say. Actually not amazing, sad and pathetic seems more appropriate.

@darshnasoni @PoliceScotland How did i know her hair colour would belong on the rainbow?

@darshnasoni @PoliceScotland #UnitedKingdom 🇬🇧 This arbitrary arrest is a clear violation of several human rights: freedom of peaceful assembly, freedom of expression, freedom of political participation, equality before the law, rule of law, separation of powers, elected democracy. Shameful police abuse!

@darshnasoni @PoliceScotland If that’s a “Breach of the peace” what do we call this ?

@darshnasoni @NickyAACampbell @PoliceScotland If she’d done what you’ve done to the picture then there would be no case to answer. Simple really.

@darshnasoni @PoliceScotland WHAT THE F***

@darshnasoni @PoliceScotland @SoniaPoulton she needs a platform. This is awful !!
