UNION CITY, N.J. (AP) — School district officials are trying to identify who watched $250 worth of pay-per-view pornographic movies using a school cable television box, officials said.

Someone after business hours used one of the five cable boxes in the Board of Education building to order the films, priced between $4.95 and $9.95.

The cable provider, Cablevision, has refunded the school district the money, and is helping to investigate the purchases.

School officials have since gotten rid of three of the cable boxes. A board official said the building had cable in case there was an emergency.
