Non-leptonic D meson decays may provide a reliable testbed for the multiquark
interpretation of light scalar mesons. In this letter we consider D_s decay and
show that a 4-quark f_0(980) meson could induce a decay pattern, which is
forbidden for a q-qbar constituent structure. Experimental tests to probe such
possibilities are within reach in the near future.
