  We report the discovery of a new gravitationally lensed radio source. Radio
maps of MG0751+2716 show four lensed images, which, at higher resolution, are
resolved into long arcs of emission. A group of galaxies is present in optical
images, including the principal lensing galaxy, with a much brighter galaxy
just a few arcseconds away. We have measured the redshift of this brighter
galaxy. No optical counterpart to the background source has been detected. Lens
models that can readily reproduce the lensed image positions all require a
substantial shear component. However, neither the very elongated lens nor the
bright nearby galaxy are correctly positioned to explain the shear. Lens models
which associate the mass with the light of galaxies in the group can produce an
acceptable fit, but only with an extreme mass-to-light ratio in one of the
minor group members.
