MEDIA, Pa. (AP) -- A second-grade teacher at a suburban Philadelphia school is accused of inappropriately touching three female students. Fifty-four-year-old Paul Hochschwender of Broomall was arraigned Wednesday on charges of institutional sexual assault, indecent assault on a person younger than 13, and corruption of minors. Hochschwender is accused of groping the girls inside a classroom at the Darby Township Elementary School. He has been a teacher there for nine years. His attorney could not immediately be reached. Delaware County District Attorney Jack Whelan said he expects more alleged victims to come forward.
