Technically there is no arrest for something which is not illegal. You can be arrested for something you didn't do but were suspected of doing but not arrested for something which you cannot be arrested for!

When you are arrested you must be told the reason why and if that reason is not valid, it is not an arrest (or it's a wrongful arrest).
