There's been a security breach and the Doctor's secrets are not safe. Following the leak of several Doctor Who season eight scripts, BBC has issued an apology and asked fans to be kind to one another and not spoil the series.

"BBC Worldwide is currently investigating a security issue around Doctor Who series eight where unfinished material has inadvertently been made public. We deeply regret this and apologize to all the show's fans, the BBC and the cast and crew who have worked tirelessly making the series," BBC said in a statement. "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."
