Using ALMA we detect for the first time CO gas in a debris disc around a solar-type star. We find the gas is of secondary origin and we probe the CO/rock composition of exocomets in the disc, finding it matches with Solar System comets. The dust continuum is resolved in an axisymmetric ring that that is consistent with grain size segregation due to radiation pressure and with a scale height<0.14
