NEW YORK (AP) — A Bronx high school teacher was arrested on child porn charges Friday after authorities accused him of using a school computer and a photograph of a former student as he enticed teenage boys to send him photographs, sometimes nude, in return for several thousand dollars in gift cards. According to a criminal complaint, about 30 nude photographs of two boys were found on a computer in his residence during a search, including 10 pictures of a 15-year-old New Mexico boy with whom he had been communicating.
