Identification required - possible POW WWII

[Darth Wookie]

I'm trying to identify the following badge which was found with my father-in-laws possessions recently. He was in the Green Howards and became a POW at Blechhammer around about 1942-44. The fist with barbed wire and, what I assume is a bird of peace, suggests to my untrained eye that it might be related.
I have no idea where to begin as this is not an area of expertise for me, however it would be of great interest to my other half to find out what it is. It may also be a red herring, who can tell.
Many thanks, in anticipation of an educated eye.
