  We present a dark matter model for explaining the observed 130 GeV photon
line from the galaxy center. The dark matter candidate is a vector boson of
mass $m_V$ with a dimensionless coupling to the photon and $Z$ boson. The model
predicts a double line photon spectrum at energies equal to $m_V$ and
$m_V(1-m_Z^2/4m_V^2)$ originating from the dark matter annihilation. The same
coupling leads to a mono-photon plus missing energy signal at the LHC. The
entire perturbative parameter space can be probed by the 14 TeV LHC run. The
model has also a good prospect of being probed by direct dark matter searches
as well as the measurement of the rates of $h \to \gamma \gamma$ and $h \to Z
\gamma$ at the LHC.
