A masked gunman has shot dead at least 14 people and wounded 50 others at a showing of new Batman movie “The Dark Knight Rises” in the US state of Colorado, media reported.
Police in the Denver suburb of Aurora said they had arrested the alleged gunman following chaotic scenes at a movie theatre at a local mall on Friday.
Aurora Police Chief Dan Oates told reporters that there was no evidence of a second gunman.
He told the news briefing that 10 people were killed on site and four others were later reported dead in area hospitals.
Denver’s’ KOA radio station said a figure in a gas mask had opened fire at the showing in a mall in the suburb of Aurora and set off a smoke or tear gas bomb.
Swedish Medical Center spokeswoman Nicole Williams said two people injured at the theatre had arrived at the hospital in critical condition.
Dozens of police were at the scene, CNN footage showed.
CNN quoted one witness as saying he saw a “guy slowly making his way up the stairs and firing, picking random people”.
It said local hospitals were alerted to a “mass casualty incident”.
