Administrator Fined for Taking 75 Theme Park Tickets Given to School Last June, a middle school on Staten Island received 370 free tickets from Six Flags Great Adventure - a boon that many grade-schoolers would consider priceless. But a quarter of the tickets never made their way to the children. Instead, an assistant principal gave 25 of them to his brother, who tried to sell them on eBay, and the rest to members of his family visiting from Puerto Rico and to a friend's Cub Scout troop, the city's Conflicts of Interest Board said on Monday. The administrator, Deric Borrero of Intermediate School 24 in Great Kills, has been fined $25,000, the board said in announcing the settlement with Mr. Borrero. The misuse came to light when a Great Adventure official investigating online bulk sales saw the tickets, with a face value of $59.99 plus tax, being offered by Mr. Borrero's brother for $29.99, according to the City Education Department's special commissioner of investigation. The company official bought a ticket and identified it through the serial number as one that the park had donated to Mr. Borrero's school. The Great Adventure official had his wife contact Mr. Borrero's brother, who told her that he had more tickets for sale and that he sold them on eBay every year, the special commissioner's office said. The tickets are marked "resale of this ticket is strictly prohibited." Mr. Borrero, 40, who has worked in the school system for 14 years, has also been placed on probation for a year, the conflicts board said. He makes $101,000 a year and has no disciplinary history. In other actions against school administrators, the conflicts board fined a Bronx assistant principal, James Mattern of Public School 168 in Mott Haven, $1,500 for paying a paraprofessional at the school to do his taxes for four years. The work did not take place on taxpayer time or involve taxpayer money, but according to New York City's conflict of interest law, government employees cannot enter into financial agreements with their subordinates. The paraprofessional, Arely Ennis, was fined $1,250.
