In the video, which was later shared widely online, Mona Prince was not wearing the kind of revealing outfit normally worn by belly dancers, but rather a loose and modest gown.
However, many on social media viewed the English literature professor's behavior as unbecoming of a university teacher.
Images purporting to show Prince in a bikini have since surfaced on social media, adding to allegations of immorality in conservative Muslim-majority Egypt.
Prince was already in trouble with the Suez University before the video surfaced. She was suspended in February over alleged poor performance. However, she told The Associated Press today that the video was being used as an excuse to push ahead with her "persecution" and later dismissal over the unconventional teaching methods she uses.

Maher Mesbah, the head of Suez University, said his decision to suspend her fell within his rights, but he would leave it up to members of faculty investigating her to decide her fate.
"Good reputation is the basis" of hiring college teachers, said the statement, published by local media. Prince is threatening legal action if she is dismissed.
