It's happened again - another teacher is accused of inappropriate conduct with a student.

This time, it's a Bergen County Math teacher, accused of having sex with a female student at Park Ridge High School.

Joseph Greco is held on $100,000 bail, charged with sexual assault and endangering the welfare of a child. He has been suspended from the school.

County Prosecutor John Molinelli says the girl told investigators she and the 27-year-old had sex between 2010 and 2011 when she was a junior and senior at Park Ridge High.
