The first search for the lepton number violating decay 𝐾&sup(+) *> *p&sup(0)*p&sup(−)*m&sup(+)𝑒&sup(+) and lepton flavour violating decays 𝐾&sup(+) *> *p&sup(0)*p&sup(+)*m&sup(-)𝑒&sup(+), 𝐾&sup(+) *> *p&sup(0)*p&sup(+)*m&sup(+)𝑒&sup(-) has been performed using a dataset collected by the NA62 experiment at CERN in 2016–2018. Upper limits of 2.9 × 10&sup(−10), 3.1 × 10&sup(−10) and 5.0 × 10&sup(−10), respectively, are obtained at 90% CL for the branching ratios of the three decays on the assumption of uniform phase-space distributions
