Abstract: A search is made for the highly-suppressed B meson decays B+ →K+K+π- and B+ →π+π+K- using a data sample corresponding to an integrated luminosity of 3.0 fb-1 collected by the LHCb experiment in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV. No evidence is found for the decays, and upper limits at 90% confidence level are determined to be B (B+ →K+K+π-) < 1.1 ×10-8 and B (B+ →π+π+K-) < 4.6 ×10-8.
