  In this paper we study the properties of QCD at nonzero chiral density
$\rho_5$, which is introduced through chiral chemical potential $\mu_5$. The
study is performed within lattice simulation of QCD with dynamical rooted
staggered fermions. We first check that $\rho_5$ is generated at nonzero
$\mu_5$ and in the chiral limit observe $\rho_5 \sim \Lambda_{QCD}^2 \mu_5$. We
also test the possible connection between confinement and topological
fluctuations. To this end, we measured the topological susceptibility
$\chi_{\mbox{\footnotesize top}}$ and string tension $\sigma$ for various
values of $\mu_5$. We observed that both string tension and chiral
susceptibility grow with $\mu_5$ and there is a strong correlation between
these quantities. We thus conclude that the chiral chemical potential enhances
topological fluctuations and that these fluctuations can indeed be closely
related to the strength of confinement.
