The Altsasu incident is a judicial case against eight young people from Altsasu, a small town in Navarre, Spain, for their involvement in a fight taking place on 15 October 2016 at a bar in which two off-duty Civil Guard officers stationed in the town and their girlfriends sustained injuries. One of the officers was knocked down, with the other victims reported to have suffered "psychological trauma". The lawsuit was initially conducted by the judge of the Spanish special court Audiencia Nacional Carmen Lamela. As of March 2018, was appointed as magistrate ahead of the trial held in late April.
