We present the recent branching fraction measurements of charmless $B^{+}\rightarrow h^{+}h'^{+}h'^{-}$ decays, where $h$ is a pion or a kaon, using 3 fb$^{-1}$ of pp collisions at $\sqrt{s}$=7 and 8 TeV by the LHCb experiment. The latest measurements of $CP$ asymmetries in charmless baryonic decays are also reported. The updated measurement of the search for $CP$ violation in $\Lambda^{0}_{b}\rightarrow p \pi^{-}\pi^{+}\pi^{-}$ decays and the first amplitude analysis of $\Xi_{b}^{-}\rightarrow pK^{-}K^{-}$, which is also the first amplitude analysis of any b-baryon decay mode allowing for $CP$ violation effects.
