We present near-IR spectroscopy of three Extremely Red Objects ( EROs ) using the OHS/CISCO spectrograph at Subaru telescope .
One target exhibits a strong emission line which we identify as H \alpha at z = 1.34 .
Using new and existing ground-based optical and near-IR imaging , and archival HST imaging , we argue that this target is essentially an elliptical galaxy , with an old stellar population of around 4 \times 10 ^ { 11 } M _ { \odot } , but having a dust-enshrouded star-forming component with a SFR of some 50–100 M _ { \odot } { yr } ^ { -1 } .
There is no evidence that the galaxy contains an AGN .
Analysis of a further two targets , which do not exhibit any features in our near-IR spectra , suggests that one is a quiescent galaxy in the redshift range 1.2 < z < 1.6 , but that the other can not be conclusively categorised as either star-forming or quiescent .

Even though our first target has many of the properties of an old elliptical , the ongoing star formation means that it can not have formed all of its stellar population at high redshift .
While we can not infer any robust values for the star formation rate in ellipticals at z > 1 from this one object , we argue that the presence of an object with such a high SFR in such a small sample suggests that a non-negligible fraction of the elliptical galaxy population may have formed a component of their stellar population at redshifts z \sim 1–2 .
We suggest that this is evidence for ongoing star formation in the history of elliptical galaxies .
