CHESTERFIELD COUNTY, Va. (WTVR) - A Chesterfield substitute teacher was let go last week after allegations were made by a recent graduate, confirmed a school spokesman.

On Tuesday night, just as candidates took off gloves and squared off at the second Presidential debate, a former Cosby High School graduate prepared his own statements.

The Cosby graduate took to Twitter with allegations that a Cosby substitute teacher had engaged in sexual activity with him, while he was a student.

The graduate posted a tease to his Twitter followers on Tuesday afternoon, saying that he would break some news. He encouraged his followers and anyone who attends or attended Cosby High School to be on Twitter, saying “it will be a treat.”

At 9:15 p.m., after announcing that he was “hammered,” the student then began releasing what he says are nude photos of a substitute teacher at Cosby High School.

He also posted alleged text message correspondence between him and the teacher, that insinuate they had sexual relations back in April, when he was a high school senior. Twitter exploded with the news.

The school was abuzz with discussion about the Twitter news. A teacher has been fired concerning allegations, but no arrests or charges have been made against any teacher.

Questions that remain are if he was 18-years-old when the incident occurred, and if the former substitute teacher will be able to pursue any type of legal action for alleged slander.

"The morning of October 12, 2012, Chesterfield Schools was made aware of an allegation made by a recent graduate regarding a substitute teacher," Shawn Smith, Spokesman, Chesterfield Schools said. "Chesterfield Police were immediately contacted."

"An immediate school investigation was conducted and the substitute teacher is no longer employed as of the end of that same day (October 12, 2012)," said Smith.

**CBS 6 is aware of the teacher's identity and has photos of the teacher but has elected not to use it until police have charged the individual.
