(from Sky News, 9/7.)
A high school production of Sweeney Todd in New Zealand went horribly wrong when a throat-slitting scene became all too real and two teenagers were sliced with a prop razor.
Students at Saint Kentigern College in Auckland were performing the opening night of the musical when the mishap happened.
Headteacher Steve Cole told radio station Newstalk ZB the razor used on stage was real, but had been bound in duct tape.
He said he had no idea what went wrong.
"It had been bound in Cellophane, bound in all sorts of things," he said.
