BETHLEHEM, Pa. (AP) - A Pennsylvania man has sued to overturn a ban that could keep him from attending his son's high school wrestling tournaments at a rival school.

Liberty High School in Bethlehem sent Ken Fenstermacher a letter barring him from its gymnasium for unspecified "offensive behavior" during a Feb. 2 match.Liberty is set to host an individual district tournament starting Friday, and the Northeast Regional Tournament on March 3. Fenstermacher's son, K.J., is a senior wrestler from Northampton Area High School, but previously attended Liberty and wrestled in grades 9-11.A Northampton County judge has scheduled a hearing Thursday at which Liberty must "show cause" why Fenstermacher should still be banned from Liberty's gym.Fenstermacher had a harassment charge dismissed after he apologized for allegedly shoving a Bethlehem Catholic coach in 2014, while his son wrestled for Liberty.
