The possibility to divide GRBs in different subclasses allow to understand better the physics underlying their emission mechanisms and progenitors. The induced gravitational collapse (IGC) scenario proposes a binary progenitor to explain the time-sequence of the GRB-SN events. We show the existence of a common behavior of the late decay of the X-ray afterglow emission of this subclass of GRBs, pointing to a common physical mechanism of this late GRB emission, consistent with the IGC picture.
