(Scroll down for video) Police launched an investigation after two teenage actors were rushed to a hospital with wounds to their throats, police in New Zealand said.
Auckland police said that the incident unfolded on Wednesday night, during a high school musical playing Sweeney Todd: The Demon Barber of Fleet Street.
At some point during the play, two 16-year-old students of the St. Kentigern College, cut their throats with a prop razor, which was very sharp.
Both students were rushed to a hospital after suffering serious injuries.
Stephen Cole, who is the principal of the school, said that the students were injured by a prop that was covered in foam and paper.
The razor was filed down and had been used during practice without incident. He called it an isolated incident, and said that the school was very upset with what happened.
When asked why a plastic razor wasn't used, Cole said that the prop had to be as real as possible.
