Abstract: We provide a series of arguments which support the idea that the peak seen in the $gamma p o K^+ Lambda$ reaction around 1920 MeV should correspond to the recently predicted state of $J^P=1/2^+$ as a bound state of $K ar{K}N$ with a mixture of $a_0(980)N$ and $f_0(980)N$ components. At the same time we propose polarization experiments in that reaction as a further test of the prediction, as well as a study of the total cross section for $gamma p o K^+ K^- p$ at energies close to threshold and of $d sigma/d M_{inv}$ for invariant masses close to the two kaon threshold.
