Collider searches for dark matter (DM) so far have mostly focussed on scenarios where DM particles are produced in association with heavy standard model (SM) particles or jets. However, no deviations from SM predictions have been observed. Several recent phenomenology papers have proposed models that explore the possibility of accessing the strongly coupled dark sector, giving rise to unusual and unexplored collider topologies. One such signature is termed as semi-visible jet (svj), where parton evolution includes dark sector emissions, resulting in jets interspersed with DM particles. Owing to the unusual MET-along-the-jet event topology this is still a largely unexplored domain within LHC. This talk presents the first results from a search for svj in the t-channel production mode in pp collisions for an integrated luminosity of 139 fb$^{-1}$ at centre-of-mass energy 13 TeV at the LHC, based on data collected by the ATLAS detector during 2015-2018.
