(DAILYMAIL) — A New York City high-school principal has been accused of sleeping with a guard, an assistant principal and a parent on campus while classes were in session, and leaving incriminating photos of the trysts on department computers.

Annie Schmutz Seifullah, 35, was escorted from Robert Wagner Secondary School of Arts and Technology, in Long Island City, Queens, Thursday, where she was principal of the 7th-12th grade.

Detectives investigating the allegations seized computers and other electronics from her office and home, which, according to the New york Post, contained pictures of her wearing only lingerie and engaging in various sex acts including a threesome.
