We present a model of leptoquarks (LQs) with a significant partial branching ratio into an extra sector, taken to be a viable dark matter candidate, other than the canonical lepton and jets final state. For LQs with mass around 500 GeV, the model reproduces the recent excess claimed by the CMS Collaboration in the \ensuremathℓ+\ensuremathℓ^\ensuremath-jj)ET final state: the event rate, the distribution in the dilepton invariant mass and the rapidity range are compatible with the data. The model is compatible with other collider bounds including LQ searches, as well as bounds from meson mixing and decays. Prospects of discovery at run II of the LHC are discussed.
