NEW YORK -- An eighth-grade teacher in New Jersey has been accused of having a sexual relationship with one of his students starting when she was 13 years old, the Bergen County prosecutor's office said Friday.

James Darden, of Cliffside Park, was arrested Friday after a woman who was a former student of Darden's told police of the alleged relationship in April, officials said.

Darden, 36, teaches at Thomas Jefferson Middle School in Teaneck.

Bergen County Prosecutor John L. Molinelli said the woman alleged that the relationship started when she was a student in Darden's eighth-grade classroom and ended when she was a high school sophomore.

The woman said that many of her trysts with Darden happened in various rooms within Thomas Jefferson Middle School, including Darden's classroom, the men's faculty bathroom and the office of the dean, according to the prosecutor. The woman also told authorities she had sexual relations with Darden in his car and his former residence in Plainfield, the prosecutor said.

The woman said Darden urged her to perform sex acts on the Internet.

"The victim also alleges that she and Darden would frequently communicate over the Internet during [the time of the affair], and that on several occasions Darden would instruct her to masturbate via a web-camera which he had provided for her," a statement from the prosecutor said.

A judge set Darden's bail at $250,000.
