PALO ALTO, Calif. -- Police said a high school biology teacher suspected of sex crimes against a 15-year-old student was arrested Wednesday night in Palo Alto.
Robert Farrell, 46, of Palo Alto, was arrested on suspicion of child molestation, sexual battery, communicating with a juvenile with the intent to commit a sex crime and arranging a meeting with a minor with the intent to commit a sex crime, police said.
Farrell is a biology teacher at Palo Alto High School, where the 15-year-old victim was a student in one of his classes and finished her freshman year earlier this month.
Farrell allegedly exchanged private messages on social media websites with the victim and set up a meeting with her on June 7, police said.
The girl, who normally helped out the teacher with chores around the classroom, agreed to meet with him, according to police.
The pair was alone in the classroom where they first engaged in a conversation before Farrell allegedly placed his hands under her clothes and touched her breasts. The teacher also allegedly placed the victim's hand on top of his clothing covering his groin and then told her to leave, according to police.
The girl's parent called police around 8:45 p.m. Monday to report their daughter was assaulted by her teacher, police said.
Farrell sent more messages to the victim on social media and made plans to meet with her Wednesday evening, when he was faced with officers who took him into custody without incident, police said.
The teacher works full-time at the high school and wasn't teaching courses during summer session, according to police.
Farrell was hired in 2012 and is in the process of getting placed on administrative leave, Palo Alto Unified School District officials said.
The district is cooperating with the police investigation and school staff have offered support to the student and her family, according to school district officials.
