A substitute teacher in the South Huntington school district was arrested Thursday on charges of possessing child pornography.

West Babylon resident Francesco Santodonato, a substitute physical education teacher at Maplewood, was arrested after an investigation by the Suffolk County computer crimes section. Police seized a computer and other media and an investigation found that Santodonato possessed pictures and videos of child pornography. He was arrested at his home at 4:26 p.m.

Dr. David Bennardo, superintendent of the South Huntington school district, said police reported that there was no evidence that any children had had any physical contact.
