A search for the decays B[0 over s]→μ[superscript +]μ[superscript -]μ[superscript +]μ[superscript -] and B[superscript 0]→μ[superscript +]μ[superscript -]μ[superscript +]μ[superscript -] is performed using data, corresponding to an integrated luminosity of 1.0 fb[superscript -1], collected with the LHCb detector in 2011. The number of candidates observed is consistent with the expected background and, assuming phase-space models of the decays, limits on the branching fractions are set: B(B[0 over s]→μ[superscript +]μ[superscript -]μ[superscript +]μ[superscript -])<1.6(1.2)×10[superscript -8] and B(B[superscript 0]→μ[superscript +]μ[superscript -]μ[superscript +]μ[superscript -])<6.6(5.3)×10[superscript -9] at 95% (90%) confidence level. In addition, limits are set in the context of a supersymmetric model which allows for the B[0 over (s)] meson to decay into a scalar (S) and pseudoscalar particle (P), where S and P have masses of 2.5 GeV/c and 214.3 MeV/c, respectively, both resonances decay into μ[superscript +]μ[superscript -]. The branching fraction limits for these decays are B(B[0 over s]→SP)<1.6(1.2)×10[superscript -8] and B(B[superscript 0]→SP)<6.3(5.1)×10[superscript -9] at 95% (90%) confidence level.
