I am using ntheorem with restatable and I would like to have a link back (hyperref) from the restated theorem to the original theorem (the restatable). MWE:

\documentclass{memoir}
\usepackage{ntheorem}
\usepackage{thm-restate}

\newtheorem{theorem}{Theorem}

\begin{document}

\chapter{One}

\begin{restatable}{theorem}{th}
Blah
\end{restatable}

\chapter{Two}

%Should link back to restatable in Chapter One
%(without extra \ref, but directly within \th*)
\th*

\end{document}


Thank you for any hints, best regards
