We present the discovery of a candidate multiply-transiting system, the firstone found in the CoRoT mission. Two transit-like features with periods of 5.11and 11.76d are detected in the CoRoT light curve, around a main sequence K1Vstar of r=15.1. If the features are due to transiting planets around the samestar, these would correspond to objects of 3.7$\pm$0.4 and 5.0$\pm$0.5 R_earthrespectively. Several radial velocities serve to provide an upper limit of 5.7M_earth for the 5.11~d signal, and to tentatively measure a mass of28$^{+11}_{-11}$ M_earth for the object transiting with a 11.76~d period. Thesemeasurements imply low density objects, with a significant gaseous envelope.The detailed analysis of the photometric and spectroscopic data serve toestimate the probability that the observations are caused by transitingNeptune-sized planets as $>$26$\times$ higher than a blend scenario involvingonly one transiting planet, and $>$900$\times$ higher than a scenario involvingtwo blends and no planets. The radial velocities show a long term modulationthat might be attributed to a 1.5 M_jup planet orbiting at 1.8~A.U. from thehost, but more data are required to determine the precise orbital parameters ofthis companion.
