A dramatic footage uploaded on YouTube shows the panic outside a theatre screening the latest Batman movie in suburban Denver soon after a gunman went on a killing spree, leaving 14 people dead and 50 injured.
People can be heard screaming as many rush out. The movie-goers look stunned and a man can be heard muttering “Oh my god”.
A man in a bloody shirt can be seen being led out by a uniformed officer.
The 2 minute 45 second long footage is the first visuals of the terrifying attack in which the gunman wearing a gas mask opened fire and set off a type of smoke or tear gas bomb at the Century Theater in Aurora Mall.
