A search for heavy neutral lepton production in decays using a data sample collected with a minimum bias trigger by the NA62 experiment at CERN in 2015 is reported. Upper limits at the to level are established on the elements of the extended neutrino mixing matrix and for heavy neutral lepton mass in the ranges 170–448 MeV/ and 250–373 MeV/, respectively. This improves on the previous limits from HNL production searches over the whole mass range considered for , and above 300 MeV/ for
