The analysis of the data on the reactions $^4$Hep -> pppnn and $^4$Hep -> dppn obtained at the 2-m ITEP liquid-hydrogen bubble chamber exposed to beams of $^4$He nuclei with momenta of 2.7 and 5 GeV/c revealed a narrow structures in the effective-mass spectra of the trinucleon system (NNN) at 2.99 GeV (for isospin T=3/2) as well as at 3.04 GeV (T=1/2). The masses of the observed structures are consistent with the masses of low-lying tribaryon resonances predicted by some theoretical models. Possible resonance nature of the structures observed is discussed.
