    We confirm changes to the band-gap of InN thin films treated in an electrochemical cell in which water electrolysis is evident. Electrical properties of the films were also affected. It is suggested that the change in the film resistivity results from hydrogen incorporation or removal during the electrolysis (dependent on sample polarity). The presence of grain boundaries is believed to enhance the penetration of chemical species into the InN resulting in a greater net change in the observed properties.
