Let D be a division ring with center k and multiplicative group D-dagger, and let N be a normal subgroup of D-dagger. Assuming that N contains a subgroup G which is nonabelian torsion-free polycyclic-by-finite (not abelian-by-finite), we construct a free noncyclic subgroup of N in terms of elements of G. We also show that if char k not equal 2, D is generated over k by the torsion-free polycyclic-by finite group G (not abelian-by-finite), and if it is possible to extend the involution x({*}) = x(-1) of G to a k involution of D, then D Z contains a free symmetric pair.
