Inclusive K{sub S}{sup 0}K{sub S}{sup 0} production in ep collisions at the DESY ep collider HERA was studied with the ZEUS detector using an integrated luminosity of 0.5 fb{sup -1}. Enhancements in the mass spectrum were observed and are attributed to the production of f{sub 2}(1270)/a{sub 2}{sup 0}(1320), f{sub 2}{sup '}(1525) and f{sub 0}(1710). Masses and widths were obtained using a fit which takes into account theoretical predictions based on SU(3) symmetry arguments, and are consistent with the Particle Data Group values. The f{sub 0}(1710) state, which has a mass consistent with a glueball candidate, was observed with a statistical significance of 5 standard deviations. However, if this state is the same as that seen in {gamma}{gamma}{yields}K{sub S}{sup 0}K{sub S}{sup 0}, it is unlikely to be a pure glueball state.
