One new pair of positive-parity chiral doublet bands have been identified in the odd-$A$ nucleus ${}^{135}\mathrm{Nd}$ which together with the previously reported negative-parity chiral doublet bands constitute a third case of multiple chiral doublet ($\mathrm{M}\chi \mathrm{D}$) bands in the $A\approx 130$ mass region. The properties of the $\mathrm{M}\chi \mathrm{D}$ bands are well reproduced by constrained covariant density functional theory and particle rotor model calculations. The newly observed $\mathrm{M}\chi \mathrm{D}$ bands in ${}^{135}\mathrm{Nd}$ represents an important milestone in supporting the existence of $\mathrm{M}\chi \mathrm{D}$ in nuclei.
