NEWPORT BEACH – One adult and three juveniles were questioned this week in the Newport Beach movie theater scare involving a leaf blower, police said Friday.

Lt. Jeff Brouwer of the Newport Beach Police Department said detectives were still determining what charges would be appropriate in the Aug. 8 incident where intruders barged into a theater during the screening of a movie at Edwards Big Newport 6, raised and revved a leaf blower and yelled.

Dozens of moviegoers in the dark, hearing the noise, later said they thought the machine was a chainsaw or gun and rushed out of the theater, with 3 experiencing minor injuries in the process.

Police believe the person with the leaf blower entered the 10:50 p.m. screening of “The Gift” through an exit door opened by someone inside the theater.

“Detectives are still putting together the case to go to the (District Attorney),” Brouwer said.

The four, described by the police as three males and one female, turned themselves in for questioning late Tuesday evening into Wednesday morning after police released surveillance photos of them earlier during the evening on Saturday at an Irvine In-N-Out brandishing and revving a leaf blower to “to elicit a reaction” from people at the restaurant, police said.

Police described the four as “fully cooperating” during the interviews.

No additional information about the identifies of the perpetrators has been released. No arrests have been made.
