  We point out that the metrics recently proposed by K. Balasubramanian and J.
McGreevy \cite{BalaMcGreevyLifshitz} as gravitational duals to Lifshitz
Chern-Simons gauge theories contain both a hidden null singularity and a region
of closed timelike curves accessible to asymptotic observers. Like the
singularity in the original Liftshitz spacetime given by Kachru, Liu, and
Mulligan, this singularity does not include large $\alpha'$ or $g_s$
corrections and hence appears to be singular in string theory as well as
classically.
