Filming of the HARRY POTTER movie has been rocked by a drugs probe - after syringes were found at the studios.

A security clampdown was immediately launched at the £110 million ($166m) children's production, and police were called in. The discovery at England's Leavesden Studios emerged after police received an anonymous tip-off that two workers there were taking drugs.

A source on the film says, "Everyone was horrified as on that day around 50 children were filming in another studio. Police were called and our own security stepped up. They have searched every inch."

A WARNER BROS statement insists, "No direct link to the production has been established." (NFA/WNTSU/PDD)
