We report on a search for the X(1812) state in the decay $B^{\pm} \to K^{\pm} \omega \phi657\times10^6$ pairs collected with the Belle detector at the KEKB collider. No significant signal is observed. An upper limit ${\cal B}(B^{\pm} \to K^{\pm} X(1812),X(1812) \to \omega \phi)<3.2\times 10^{-7}$ (90% C.L.) is determined. We also constrain the three-body decay branching fraction to be ${\cal B}(B^{\pm} \to K^{\pm} \omega \phi)$ 1.9 (90% C.L.).
