Can the police take you to jail for an eviction if you haven't went to court?

Only if you want to stay! If you agree to leave, there is no dispute for a court to bother with.

It is best to go to court to defend yourself and to plead your case, but if you just want to bail, you can do that too and the judge will adjudicate against you and your lease (if it's still intact) will be negated.
