Member of security appeared to be injected -Houston Police Chief

A day after a stampede of fans pushing toward the stage during rap star Travis Scott's Astroworld festival in Houston killed at least eight people, Houston Police Chief Troy Finner told reporters, "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 or grab a citizen and he felt a prick in his neck."
