Possibility of an axial vector isoscalar tetraquark udss is discussed. If a f_1 meson in the mass region 1.4-1.5 GeV consists of four quarks nsns, the mass of the isoscalar udss(v^+-meson) state with J^P=1^+ is expected to be lower than that of the f_1 meson. Within a flux-tube quark model, a possible resonant state of udss(J^P=1^+) is suggested to appear at〜1.4 GeV with the width O(20〜50) MeV. We propose that the v^+-meson is the good candidate for the tetraquark search, which would be observed in the K^+K^+π^- decay channel.
