A resonance search has been made in the K0s-p, K0s-pbar and K+p invariant-mass spectra measured with the ZEUS detector at HERA using an integrated luminosity of 121 pb-1. The search was performed in the central rapidity region of inclusive deep inelastic scattering at an ep centre-of-mass energy of 300--318 GeV for exchanged photon virtuality, Q2, above 1 GeV2. The results support the existence of a narrow state in K0s-p and K0s-pbar decay channels, consistent with the pentaquark prediction. No signal was found in the K+p decay channel.
