A student magazine at Britain's Cambridge University has raised controversy by publishing a topless picture of a female undergraduate.

Vivid Magazine, which has a distribution of more than 5,000 including students from all of the university's 31 colleges, printed the photo of the blond student, whose name was not printed, wearing only a black lacy thong and stockings while straddling the historic Clare College bridge, The Daily Telegraph reported Friday.

The photograph is believed to mark the first time a Cambridge student has appeared topless in a university publication.

"I can't believe she agreed to pose for the magazine. Everyone has been talking about it. I'm sure she must really regret it now," a King's College student said.

The Daily Mail said university officials are investigating ways to avoid further incidents that could embarrass the school.

The editors of Vivid Magazine declined to comment on the reactions to the photograph.
