BBC bosses have appealed to Doctor Who fans not to reveal spoilers for the upcoming eighth season of the cult sci-fi show, after scripts for five new episodes leaked online.
The material had reportedly been made public after the documents were sent to employees at the new BBC Worldwide Latin America headquarters in Miami, Florida for translation.
Now BBC chiefs are hoping Doctor Who devotees will help to keep the storyline for new lead actor Peter Capaldi's debut as the Time Lord under wraps until the season begins airing in the UK in August.
"Unfinished material has inadvertently been made public," a statement released by BBC executives reads.
"We deeply regret this and apologise to all the show's fans, the BBC and the cast and crew who have worked tirelessly making the series.
"We would like to make a plea to anyone who might have any of this material and spoilers associated with it not to share it with a wider audience so that everyone can enjoy the show as it should be seen when it launches.
"We know only too well that Doctor Who fans are the best in the world and we thank them for their help with this and their continued loyalty."
