Abstract: This work is dedicated to the search for a $\pi\Lambda N\!-\!\pi\Sigma N$ resonance $\mathcal{Y}$ with the quantum numbers ($Y,I,J^P$) = (1,$\frac{3}{2}$,$2^+$). The double charged $\Sigma(1385)N\!-\!\Delta(1232)Y$ quasibound state was looked for in the reaction $pp\rightarrow \mathcal{Y}^{++}K^0$ with its unique decay into $\Sigma^+$ and proton measured with the HADES setup at a kinetic beam energy of 3.5~GeV. The analysis including background determination and a description of the data with a $K^0_S$ Monte Carlo cocktail are presented.
