The authors have obtained new high-resolution radio observations of NGC 7674, using the European VLBI network and the VLA, and optical spectroscopic observations using the Isaac Newton Telescope. The radio maps reveal a triple radio source with a total angular extent of about 0.7 arcsec, and provide evidence that the radio emission is powered by collimated ejection. In the plane of the sky, the ejection axis appears roughly perpendicular to the galactic rotation axis. Although the dominant radio components are separated by 0.5 arcsec, the broad [O III] λ5007 line emission is confined to within about 0.25 arcsec of the continuum nucleus. The authors discuss possible implications of this result.
