This is a very early Phantom story of Indrajal Comics (1965). In this story Diana convicted for theft of valuable black pearl necklace, which was actually stolen by a small trained bird of Pashuraj (King of the animals). Pashuraj was a old crazy man who trained different wild animals (Lion ,Tiger, Monkey Birds etc) to avenge from the human who tortured innocent animals.
You have to read full graphic comic to know How Phantom rescued Diana from false allegation? and what happened to Pashuraj and his animals?.
