We report the results of low-temperature specific-heat, magnetization, and X-ray diffraction measurements on a bismuth oxyhalide (BiOCl) single crystal. We conclude that BiOCl in temperature region 150-230 K shows "antiferroelastic-paraelectric" phase transitions at critical temperatures T_{c1} = 167.5 K and T_{c2} = 214.6 K, respectively.
