The double-charge-exchange reaction {sup 3}He(K{sup {minus}}, {pi}{sup +})Xn was studied at p{sub K}- = 870 MeV/c. In the missing mass range below the sigma-nucleon production threshold (3075 MeV/c{sup 2}) events were detected and attributed to the two-nucleon reaction pp(K{sup {minus}}, {pi}{sup +}){Lambda}n. This reaction and mass range is supposed to be a fertile field for a search for the I = 1/2, L = 1 ({sup 1}P{sub 1}) spin-singlet dibaryon suggested as the lowest mass S = {minus}1 dibaryon of bag model predictions. We find no need to invoke such an object to account for the observed events below {Sigma} production threshold.
