Oh, she was sentenced for rioting. I'm at work right now, but I'll try to find the article again after work so I can send you the link (I read about it in the German newspaper Die Welt).

The tl;dr is that the son of Ruandan immigrants took a taxi to drive to a dance course for little girls and started stabbing them, killing three nine-year old girls and injuring several others. Riots broke out among the indigenous population, which were promptly decried as right-extremist violence by the Starmer regime, which promised to bring the full force of the courts on them.

Rumors in the comments sections have it that Muslim mobs that commit violence against the protesters aren't being touched by the police, nor is any of them getting arrested. Looks like the government is waging a war against its own electorate, but I'm sure that's just conspiracy talk.
