Recently observations of a narrow baryonic state decaying to charged kaons and neutrons or $K^0_s$ mesons and protons have been reported by several experiments. This resonance could be identified as a candidate for the exotic
$ heta^+(1530)$ pentaquark state.
The H1 results on the search for the $ heta^+(1530)$ and its antiparticle in
the invariant mass combinations of $K^0_s$ mesons with protons and
antiprotons in deep inelastic scattering at HERA are reported.
