There is strong evidence that the Standard Model of particle physics is incomplete. The lack of evidence for any new particles had renewed interest in theories postulating the existence of a Dark Sector. The precise manifestation of these particles is entirely unknown, but at low masses a dominant decay channel would be into a dimuon pair. To that end, a search for a dark sector particle, $\chi$, is performed by studying the decay $B^0 \rightarrow K^*(892)^0\mu^+\mu^-$ and $B^+ \rightarrow K^+\mu^+\mu^-$ for candidates consistent with $\chi \rightarrow \mu^+\mu^-$. Limits on the branching fraction of both decay modes are set, as functions of both the mass and \chi lifetime, in a fully frequentist manner.
