She was arrested and charged, and took the option of receiving an ‘adult caution’. (Mentioned in this Guardian article.)

I think it would be misleading to say that’s ‘a warning and nothing more’.

If she hadn’t opted for the ‘adult caution’ - which requires that you don’t deny committing the offence - then she’d still be facing charges and gaol time.

So I reckon ‘complete lie’ might be a bit uncharitable, when really the information is just out of date.

Thanks for raising the point though, good to hear this protester doesn’t have legal proceedings hanging over their head.
