Suffolk police have arrested a Holbrook teenager who they said apparently hacked into Sachem school district computers and posted online the personal data of thousands of students.
Police said Matthew Calicchio, 17, of Roberts Street, illegally accessed and downloaded Sachem students' records in 2012 and 2013. From July through November of this year, police said, Calicchio posted the information online at 1Apps.com, a free site, and Sachemunspun.com, a school district and community forum run by resident Fred Gorman.
Calicchio, who had been a Sachem High School North student at the beginning of the 2013-14 school year, was being held overnight at the Fifth Precinct after his arrest Friday. He is charged with felony computer trespass and is scheduled to be arraigned in First District Court in Central Islip Saturday.
The district complained to police after learning on Nov. 8 that some information had been posted on a Web page, but it was unclear Friday what led police to Calicchio, whose attorney and family could not be reached for comment.
The data that were posted included a list of 15,000 student names dating back to the early 2000s and school identification numbers and lunch designations.
There were also another 12,000 names and school identification numbers posted, but only about 900 of those names were not repeats, according to Sachem school district Superintendent James Nolan.
Student records for about 360 Sachem High School East graduates from 2008 were also posted, along with a report on about 130 Sachem High School North students in the 2010-2011 year who received "instructional services in an alternative setting," Nolan said in a statement on the district's website.
