The structure of the high spin states above the 28${}^{-}$ isomer in the odd-odd ${}^{152}$Ho nucleus was investigated using the GASP $\gamma$-ray spectrometer coupled to the recoil mass spectrometer CAMEL. The ${}^{152}$Ho nucleus was populated through the ${}^{120}$Sn${(}^{37}$Cl,5$n)$ fusion reaction at a beam energy of 187 MeV. A complex level scheme above that isomer was established up to an excitation energy of 13 MeV and $I\approx$ 40$ħ$. No rotational bands were observed.
