  "comment": "Version resubmitted to MNRAS. 29 pages, 8 figures, 6 tables. Small changes to the abstract. Sections 3 and 4 slightly expanded and modified. Results unchanged. Section 4 has been broken into smaller subsections. Figure 6 improved. Added Table 6 with a summary of the models. Typos and references fixed",

  "abstract": "We present a wide dataset of gamma-ray, X-ray, UVOIR, and radio observations of the Swift GRB100814A. At the end of the slow decline phase of the X-ray and optical afterglow, this burst shows a sudden and prominent rebrightening in the optical band only, followed by a fast decay in both bands. The optical rebrightening also shows chromatic evolution. Such a puzzling behaviour cannot be explained by a single component model. We discuss other possible interpretations, and we find that a model that incorporates a long-lived reverse shock and forward shock fits the temporal and spectral properties of GRB100814A the best.",
