A 75-year-old woman and three students at a Scottsdale high school were arrested for simulating a shooting and kidnapping, police said.

The incident marks the second time police responded to what they believed was an actual crime involving Desert Mountain High students but turned out to be a video project for a criminology class.

Last January, Scottsdale police were called to a simulated carjacking near the high school and officers ended the production when they arrived with their guns drawn.

On Sunday, three 15-year-old girls who are sophomores at Desert Mountain were arrested on suspicion of disorderly conduct after a concerned neighbor called 911.

Police said 75-year-old Marilyn Miller, who was videotaping, also was arrested on suspicion of contributing to the delinquency of minors.
