Batman premiere shooting: gunman kills 14 people at Denver cinema

At least 14 people have been killed in a shooting at Batman film The Dark Knight Rises premiere in Denver, Colorado, police say.

About 50 people have been injured in the incident, police say.

Witnesses say a gunman wearing a gas mask opened fire at the cinema complex in Aurora, at a midnight showing of The Dark Knight Rises.

There are reports the gunman released a smoke bomb during the incident. Police say they have one suspect in custody. Many ambulances are at the scene.

The Swedish Medical Center, not the area’s main hospital, said it had received three gunshot victims.

A witness told 9News that during a shooting scene in the film he heard loud bangs and a lot of smoke and initially thought they were live special effects put on by the cinema.

Projectiles came through the wall from the neighbouring theatre screening, the witness said.

CNN quoted one witness saying: “A guy slowly making his way up the stairs and firing – picking random people.”
