A New York principal could face misconduct charges following allegations that she had sex with co-workers and a student's parent on campus while school was in session.

Annie Schmutz Seifullah, 35, was removed from the Robert Wagner Secondary School of Arts and Technology in Long Island City on May 1 after her jilted ex-boyfriend, a single father, went to police with shocking allegations, and images to back them up, the New York Post reports.

The man told cops that Seifullah had cheated on him with a NYPD security officer who worked at the school, and with a visiting assistant principal -- both times at the school. In audio and video recordings provided by her accuser, a woman identified as Seifullah admits to the acts.

The New York Post reports:

“I don’t know what I was thinking. I don’t know why I thought it was OK,” she tells the furious dad in the taped conversation, after he accuses her of cheating on him.

“You gave him [expletive deleted] while my child was in the building,” he roars at one point.

The man went to police after his relationship with Seifullah unravelled. According to the New York Post, he gave investigators three laptop computers owned by the Department of Education that contained photos and video of the woman in racy lingerie and in various sex acts, including a threesome. In one photo obtained by the Post, Seifullah appears posing in lingerie.

Police said they removed computers and other electronics from the woman's office and home.

NYC teachers and administrators aren't banned from dating each other, but favoritism or mistreatment could lead to a citation. Having sex in school or putting sexual images on school computers can lead to misconduct charges.

WPIX reports than an investigation by the Department of Education is underway.

"We are appalled by these disturbing allegations and acted swiftly to remove the principal while the matter is under investigation," a Department of Education spokesman said, according to Gothamist. "This type of alleged behavior is completely unacceptable for any DOE employee."
