Two Roman Catholic school workers from New Jersey have pleaded not guilty to charges of having sex with female students during a high school's class trip to Germany.
Thirty-one-year-old Artur Sopel was vice president of operations at Paramus Catholic High School, and 27-year-old Michael Sumulikoski was a substitute teacher and assistant football coach until they were suspended last month.
Sumulikoski is accused of having sex with one female student on the February trip.
Sopel is accused of engaging in sexual activities with two female students in Germany and having sex with another female student in 2010.
Both are charged with sexual assault, child endangerment and hindering apprehension.
Sumulikoski's lawyer told The Record newspaper he's investigating whether New Jersey has jurisdiction over acts that allegedly occurred in Germany.
Authorities have not released the girls' ages.
