We perform a calculation for the three body NKbarK scattering amplitude by using the fixed center approximation to the Faddeev equations, taking the interaction between N and Kbar, N and K, and Kbar and K from the chiral unitary approach. The resonant structures show up in the modulus squared of the three body scattering amplitude and suggest that a NKbarK hadron state can be formed. Our results are in agreement with others obtained in previous theoretical works, and reinforces the claim for a new N^* resonance around 1920 MeV with spin-parity J^P=1/2^+.
