Well in most places in the world the police can arrest / detain you for pretty much anything, or they can find/create a reason to arrest you. Question then becomes a) will the charges stick b) will you be able to seek redress afterwards. Edit: not saying the UK doesn’t have some stupid laws on the books, or that politicians are not adding more stupid laws to the books, just that even in the US, the land of the free, a bad cop or a prosecutor looking for a promotion can make the next few months or even years hell for you if they wanted it.
