We give necessary and sufficient conditions for a finite subgroup $H$ of a hyperbolic group $G$ to contain a free subgroup $F$ of rank two in $G$ such that $F$ and $H$ generate a free product $F*H$. A verification algorithm for these conditions is pointed out.
Keywords: hyperbolic group, finite subgroup, free product.
