Recently, an axially symmetric spacetime with causality violation is appearedin Ref. [1]. There, author presented a type III metric with vanishingexpansion, shear and twist. The matter-energy represents a pure radial fieldwith a negative cosmological constant. The spacetime is asymptotically anti-deSitter space in the radial direction. Actually, this work with different forthe metric was already published in Ref. [4]. Therefore, the current paper Ref.[1] is a duplicate one of the previous work.
