as a component of non-baryonic dark matter has become a focal point of modern particle physics [@review]. There are several complementary experimental and observational approaches to WIMP detection [@WIMPS]. Direct detection experiments probe the terrestrial scattering of WIMPs with nuclei and typically require low radiation environments to keep backgrounds under control. High energy colliders such as the Tevatron and the LHC offer the possibility of producing WIMPs and measuring their properties in the laboratory, provided the challenging missing energy signatures can be disentangled. Indirect searches for dark matter annihilating into gamma and cosmic rays in the galactic halo are also promising, although susceptible to various, often uncertain, astrophysical backgrounds. Finally, neutrino telescopes such as Super-Kamiokande and Ice Cube can search for indirect evidence of the annihilation of WIMPs captured in the core of the Sun and the Earth, in the form of an observable muon signature arising from neutrino charged current scattering in the detector. While the latter two examples are well-known indirect signatures for any thermal relic WIMP dark matter candidate, more generic WIMPs forming part of a larger dark sector can lead to further novel signatures. In this paper, we demonstrate that models of secluded dark matter [@PRV]
