The NA48/2 experiment at CERN collected in 2003-2004 a large sample of charged kaon decays with multiple charged particles in the final state. A new upper limit on the rate of the lepton number violating decay K+- --> pi-+ mu+- mu+- obtained from this sample is reported. Searches for two-body resonances in the K+- -->pi mu mu decays (including heavy neutral leptons and inflatons) in the accessible range of masses and lifetimes are presented.
