Twilight Saga: Breaking Dawn Set Guarded By Police
Security in Canada has been tightened after pics of the film leaked...
Off-duty police officers are now thought to have surrounded the set, where R-Pattz and Kristen are allegedly filming the Breaking Dawn wedding scene in the Canadian mountains.
It has been reported that sheets and umbrellas are also being used to protect the set in order to avoid aerial shots being taken.
Summit Entertainment previously expressed their anger after various snaps from Breaking Dawn were leaked, stating they were "heartbroken" that the pictures had become public before the movie's release.
Pattinson, who plays Edward Cullen in the films, also branded those who stole the pics as "idiots", urging Twihard fans to find and "destroy them."
