A Lehigh University student from Montgomery County is accused of wandering naked through a women’s dormitory while high on the drug LSD. 19-year-old Nicholas Tanen of Indian Crest Drive in Harleysville is charged with indecent exposure, indecent assault and other offenses. Court documents say he exposed himself to at least three female students, and then pulled one of them to the ground on top of him. After leaving a dorm room around 5:00pm Saturday, he allegedly pulled a fire alarm. When police and firefighters arrived, he began fighting with them.
