The incident occurred in the city of Haifa, according to Life.ru. The sixth graders received an unusual surprise at their class graduation party. The discs which were supposed to have a film about their school instead had pornographic footage on them.
The parent of one of the students was shocked to discover the actual content of the DVD. Upon this unusual discovery they rushed to inform other parents.
Angry parents appealed to the board of the school for clarification. The board explained this incident saying that it could have happened because the company which was recording the school film on the DVDs was reusing the discs on which earlier adult films were being recorded.
The school promised to correct this error as soon as possible and offered their apologies.
