UNION CITY, N.J. – Investigators trying to determine who ordered more than a dozen porn movies in the Board of Education building have come up empty handed.

Nobody will face disciplinary action because an investigation by the law firm Nukk-Freeman & Cerra was unable to uncover who ordered the “on demand” pornography in February, an attorney for the firm said.

But responding to recommendations of the report, the board has been introducing new procedures at the Board of Education offices to restrict access to cable television and monitor misuse of video equipment, officials said.

“We will put into place the recommended new policies that will prevent this from happening again,” Superintendent of Schools Stanley Sanger said in a statement.

The law firm grilled several staff members in connection with the unauthorized purchases, but a district spokesman said that investigators could not identify the culprit or culprits because access to the cable boxes had been unrestricted.

The report, sent to the Board of Education on May 9, recommended limiting access to the cable system’s “on demand” programming, officials said.

New controls have been introduced, and eight cable boxes have been removed so only Sanger and the Assistant Superintendent of Schools Gerald Caputo have access.

To more easily identify future offenders, surveillance cameras will be installed throughout the Board of Education offices, officials said.

In all, 17 programs that cost $174.68, ordered between Monday, Feb. 12, and Friday, Feb. 16, showed up on the Board’s Cablevision bill.

School was in session that week and many of the films were ordered during the day, although no classes meet in the Board of Education building.

A spokesman for the company said that the location of the cable box used to purchase the digital movies could not be determined.

The invoice showed that most of the orders were pornographic titles priced at $8.95 or $9.95. They also included a pro-wrestling event and a racy Jerry Springer special.

Officials say they have cable-equipped televisions for educational purposes and for emergency preparedness.

Cablevision, the district’s provider, issued a refund to the district after the theft was brought to light.
