Police arrested a Plano high school teacher on suspicion of alleged sexual assault of a child.
Addison Colby Green, 26, a teacher at Shepton High School in Plano, is accused of sexually assaulting a 16-year-old.
The victim was not a student at Shepton High. Police said there are no other known victims.
According to the arrest affidavit, Richardson police were called to Methodist Regional Medical Center, where a 16-year-old boy told officers Green inappropriately touched him.
"The victim reported to us there had been some inappropriate touching, and DNA evidence was obtained two days later, corroborating his account," said Jonathan Wakefield, an investigator with Richardson police.
The incident allegedly happened at Green's home. The victim told police he had known Green for seven months.
Green was arrested on campus last week. The district placed him on administrative leave and removed his page from the district's website.
Shepton parents and students received a letter about Green's arrest. Students said Green was a science teacher and said his classes were split up after his arrest.
