A man was arrested on a drug charge this week while in an Aberdeen hotel room with Rumer Willis, daughter of actors Bruce Willis and Demi Moore, according to Aberdeen police.
Chief Randy Rudy confirmed the story, first reported by Access Hollywood, about the incident in the La Quinta Inn.
The actress, 18, is in the area for the shooting of From Within, a psychological thriller co-starring Thomas Dekker of NBC's Heroes.
Willis was not arrested. Rudy said that a "key grip," a production worker on the film, was arrested on a marijuana-related charge.
"What I was told by my officer was that she was in the periphery and was not related to this arrest in any way," Rudy said.
Shooting of the film, about a small town where it appears that teenagers are committing suicide, is to continue through Aug. 9 in and around Havre de Grace.
Director Phedon Papamichael is known for his cinematography in Walk the Line, Sideways and Pursuit of Happyness.
