At least two investigations and one civil lawsuit were underway on Sunday into the deadly stampede during rap star Travis Scott's Astroworld music festival that killed at least eight people and injured dozens in Houston, US.

Two of the victims were teenagers, aged 14 and 16, caught in the crushing surge of the crowd as Scott continued to perform, completing his set even after noticing fans were receiving medical treatment. Scott, the headline act and a hometown star who founded the Astroworld festival in 2018, later said he was unaware of the severity of the situation.

Houston city police chief Troy Finner said his department had opened a criminal investigation by homicide and narcotics detectives, following reports that somebody in the audience had been injecting people with drugs.
