Eight people were killed and dozens injured during a crowd surge at a music festival in Houston, Texas on Friday night.
The age range of those who died is between 14 and 27, with the second teenage victim being 16-years-old.
Thirteen of the twenty-five people taken to hospital were still receiving treatment, with five of them under the age of 18.
The surge towards the stage at the Astroworld festival took place just after 9pm, while rapper Travis Scott was performing.
The crowd movement caused panic and injuries, then people began to fall out and become unconscious, which created additional panic.
The show was immediately called off and the festival was cancelled.
Police have launched a criminal investigation.
Houston police chief Troy Finner said: “I think that all of us need to be respectful of the families and make sure that we follow the facts and evidence and that’s what we’re trying to do here in the Houston police department.”
“I will tell you, one of the narratives was that some individual was injecting other people with drugs.”
“We do have a report of a security officer, according to the medical staff that was out and treated him last night, that he was reaching over to restrain a citizen and he felt a prick in his neck. When he was examined he went unconscious. They administered Narcan, he was revived and the medical staff did notice a prick that was similar to a prick that you would get if somebody is trying to inject.”
