An investigation into alleged drug use at Leavesdon Studios in England, where Harry Potter and the Sorcerer's Stone is being shot, has turned up a number of syringes, forcing a tightening of security procedures at the studios, according to published reports. Today's (Monday) London Daily Sun quoted a Warner Bros. spokeswoman as saying Sunday night that the studio regarded the discovery as "a very serious matter." She added: "Our paramount concern is for the safety and protection of the cast and crew of Harry Potter."

According to the Sun, the drug paraphernalia was discovered in a nearby studio at about the same time that 50 children were being filmed on the Potter set. "Everyone was horrified," an insider told the newspaper.

A Warner Bros. statement said: "No drugs were found on the Potter set and no direct link to the production has been established."
