Mystery Arabic badge - Sudan Police?
 

I’ve just received this cap badge from a friend, he doesn’t know what it is but, although I believe it to be Sudan Police, I can find nothing to back this up. It is chrome, 30 x 39mm, with E-W lugs. I have seen one before and should know where it is from but I’m drawing a blank at present - can anyone help me please?

As always any help will be greatly appreciated
