  Let $D$ be a division ring with center $F$, and $G$ a subnormal subgroup of
$D^*$. We show that if $G$ is a locally solvable group such that $G^{(i)}$ is
algebraic over $F$, then $G$ must be central. Also, if $M$ is non-abelian
locally solvable maximal subgroup of $G$ with $M^{(i)}$ algebraic over $F$,
then $D$ is a cyclic algebra of prime degree over $F$.
