In this paper, we present radio and high‐energy observations of the  INTEGRAL  source IGR J21247+5058, a broad line emitting galaxy obscured by the Galactic plane. Archival Very Large Array radio data indicate that IGR J21247+5058 can be classified as an Faranoff–Riley type II Broad‐Line Radio Galaxy. The spectrum between 610 MHz and 15 GHz is typical of synchrotron self‐absorbed radiation with a peak at 8 GHz and a low‐energy turnover; the core fraction is 0.1 suggestive of a moderate Doppler boosting of the base of the jet. The high‐energy broad‐band spectrum was obtained by combining  XMM–Newton  and  Swift /X‐Ray Telescope (XRT) observation with  INTEGRAL /Image on Board Integral Satellite (IBIS) data. The 0.4–100‐keV spectrum is well described by a power law, with slope  Γ= 1.5 , characterized by complex absorption due to two layers of material partially covering the source and a high‐energy cut‐off around 70–80 keV. Features such as a narrow iron line and a Compton reflection component, if present, are weak, suggesting that reprocessing of the power‐law photons in the accretion disc plays a negligible role in the source.
