Students at Oprah’s dream school in South Africa in sex scandal. Again. or Still. or Whatever.

Oprah Winfrey’s girls-only boarding school in South Africa has landed in another sex scandal in less than two years.

Seven students at the Oprah Winfrey Leadership Academy for Girls in Johannesburg, South Africa, were involved in sexually harassing their fellow pupils.

The students have been punished for violating the code of conduct at Oprah Winfrey's school for disadvantaged girls in South Africa, the second controversy to hit the fledgling institution since it opened in 2007. Winfrey representative Don Halcombe said Wednesday that four students were expelled and three were suspended last week from her Leadership Academy for Girls outside Johannesburg after being accused of sexually harassing their fellow pupils.

Halcombe declined to say what led to the violations because there are minors involved.

According to the South African media seven girls were accused of trying to force students into relationships and to engage in sexual contact.

A girl of 15 was found guilty of preying upon another student and forcing other girls to conceal the truth from investigators. Other girls were caught fondling each other or trying to get other girls to join them in lesbian liaisons.

The incident is not the first scandal at Winfrey’s dream school. Shortly after the grand opening of the school two years ago, a female school staffer was accused of physically and sexually abusing students. She is still on trial for these crimes.

Winfrey poured $40 million into the 28-building campus on 22 acres. It has computer and science labs, and a library, theater and wellness center.

The school was inspired by Winfrey’s own "humble beginnings" and disadvantaged background. It is the fulfillment of a promise she made to former South African President Nelson Mandela. Winfrey’s goal is to provide educational and leadership opportunities for academically gifted girls from impoverished backgrounds in South Africa.

In 2007, there was an intensive application process among 3500 applicants to determine which of the 152 girls would be admitted to the school.

Winfrey herself conducted the final interviews to determine which students she felt “had leadership potential to change the world.”
