Officer Lewis was involved in the December 2017 arrest of Anthony Mason at Wheaton Warrenville South High School. Mason alleged that Lewis, along with other officers, used excessive force during the arrest, including placing him in a chokehold and violently twisting his arms behind his back. Mason filed a lawsuit claiming racial discrimination and excessive force. The case was reviewed in May 2021, with the court allowing the equal protection claim against the school’s Dean to proceed, but the outcome regarding Officer Lewis was not specified in the available information.
