PALATINE, Ill. -- A sexually explicit email was sent to thousands of students in the Northwest suburbs.
District 211 officials say an inappropriate e-mail was sent Tuesday night.
It was received by a large number of students at Fremd High School in Palatine.
The images are too graphic to show.
The district is working with Palatine police to determine how the breach happened.
The principals at Fremd and Palatine High Schools sent an e-mail to parents Wednesday, explaining what happened.
They also warned parents and students about the dangers of opening unsolicited emails from unknown sources.
