  The branching ratios for the neutral and charged B decay channels to $\eta'
K$ and $\eta K^*$ are well above the Standard Model expectations. Moreover, the
mixing-induced CP asymmetry in $B \to \phi K_S$ is incompatible to that found
in $B\to J/\psi K_S$. We investigate whether a flavour-specific tree-level
$b\to s \bar{s} s$ operator coming from R-parity violating supersymmetry can
resolve both these discrepancies, without jeopardizing those results which are
in agreement with the Standard Model. We found that it is possible to have a
parameter space satisfying all these requirements, including that of a low
strong phase difference compatible with the color transparency argument.
Furthermore, we put a robust bound on the relevant coupling, which is two
orders of magnitude better than the existing one.
