AGASA has detected an excess of events coming from the central regions of the Galaxy at energies around 1 EeV. This excess can be divided into two components: one that fits a dipole distribution and can be attributed to the diffusion of heavy galactic nuclei, and another one, restricted to approximately the inner 30 degrees, that has remained so far unexplained. Here we propose that the latter component is due to the production of cosmic rays by the last few Gamma Ray Bursts (GRB) in our Galaxy. The basic idea is that protons accelerated inside GRB are effectively ejected as neutrons, which in turn build up through decay a population of protons that is diffusively trapped for some time in the inner few kpc of the Galaxy. These protons constitute an extended source of second generation neutrons which roughly trace the star formation rate in our Galaxy. We demonstrate that this model leads to a successful interpretation of the data.
