AURORA, Colorado (AP) — U.S. police say as many as 20 people were injured when shooting erupted around midnight Thursday at a suburban Denver movie theater.
The Aurora, Colorado police dispatch office said that there are fatalities but they don't know how many.
Calls to police about the shooting started coming in about 12:30 a.m. Friday from a mall theater that was showing the Batman movie "The Dark Knight Rises," the office said.
One person has been arrested but police did not have any other details.
"The scene is still very active and we have little information for release at this time," police spokeswoman Cassidee Carlson said in a brief news release.
Witness Hayden Miller told KUSA-TV that he was inside Theater 16 and heard several shots.
"Like little explosions going on and shortly after that we heard people screaming," he told the station.
Hayden said at first he thought it was part of a louder movie next door. But then he saw "people hunched over leaving theater."
Spokeswoman Nicole Williams said that two people in critical condition had been rushed to the nearby Swedish Medical Center.
She said emergency crews told her staff to prepare for several more patients from the shooting scene.
"We're on standby to receive," she said. "Police said they could have as many as 20 or more (patients)."
Williams said she was told that "somebody opened fire with some sort of weapon during the "Dark Knight" movie.
Aurora is located on the outskirts of Denver, about 10 miles southeast of downtown.
