If he's released it will because he will have served his time and been cleared in the five cases, fortunately we're not locking people up for reasons apart from guilt.
Actually we do. And so does the German Federation. It is known as Preventative Custody and is in place to protect the public from persons who are considered too dangerous to be freed.

Preventive detention is an
imprisonment that is putatively justified for non-
punitive purposes, most often to prevent further criminal acts.
Preventive detention sometimes involves the detention of a convicted criminal who has served their sentence but is considered too dangerous to release.
Remand or pre-trial detention and
involuntary commitment are sometimes considered a form of preventive detention.

In
Germany, preventive detention (German:
Sicherungsverwahrung) is an indeterminate sentence that follows regular imprisonment, imposed as part of a criminal sentence.
[10]
Sicherungsverwahrung is imposed in the original judicial sentence. It could formerly be subsequently imposed under certain circumstances, but the practice of subsequent incapacitation was ruled a violation of Art 7 of the
European Convention on Human Rights by the
European Court of Human Rights.
[11] The
Federal Constitutional Court of Germany also issued a verdict on
Sicherungsverwahrung in May 2011, deeming it unconstitutional.
[12] In response, a new law regulating
Sicherungsverwahrung was passed in November 2012.

In 2023 27 supporters of
Last Generation (climate movement) were preemptively imprisoned after the group announced protests of the
International Motor Show Germany.
