Charged: Rachel Farrell, 25, is alleged to have carried out an extended affair with an 11th grade pupil at Bangor Area High School in Pennsylvania . A former high school teacher has been charged with having sex with a 17-year-old student on 'numerous occasions'. Rachel Farrell, 25, is alleged to have carried out an extended affair with an 11th grade pupil she was teaching reading to at Bangor Area High School in Pennsylvania. She has since resigned and has now been charged with three counts of corrupting a minor. The case is the latest to concern a female teacher who has been jailed for, or accused of, having sex with a student. Police believe Farrell also had sexual relationships with up to three other 17-year-old students, Northampton County District Attorney John Morganelli said yesterday. She faces further charges should these teenagers decide to testify against her. Mr Morganelli said: 'This particular case was the case we could bring. This may be it. 'It may be that we just don't bring other cases for reasons of lack of cooperation from the alleged victims. 'Farrell forfeited her career. [Sleeping with an underage student] is just not right, it's wrong and it constitutes a crime under our crimes code.' Farrell taught at Bangor Area High School under her maiden name, Rachel Warner, but has been on administrative leave since December when the allegations first emerged. Mr Morganelli said she admitted to both police and her employers that she had slept with two 17-year-old students. She married in June 2010 and is accused of conducting an affair with the student between August of that year and January 2011. Police said the teenager, now 18, admitted having sex with Farrell at 'numerous times at many different locations' such as secluded parking spots. Their relationship is said to have begun after the pair began talking on Facebook and through text messages. Bangor .

Police believe Farrell also had sexual relationships with up to three other 17-year-old students at Bangor Area High School (pictured) Farrell, of Palmer Township, is free on $5,000 bail. She has cooperated with police, but the investigation is ongoing, Mr Morganelli said. The age of consent in Pennsylvania is 18 for the corruption of minors.
