Deutscher Jujutsu Verband

[Mr. President]

Has anyone ever heard/experimented/knows someone who dabbled in German jujutsu? According to the internet, it's a rather eclectic approach to hand to hand combat. While primarily focused on Jujutsu/Aikido/Judo techniques, it also incorporates moves from FMA, BJJ and CMA. Taught to German polizei, apparently.

Can anyone shed some light on this?
