Astroworld security officer 'felt a prick in his neck'
Police are investigating claims a security officer was injected in the neck while trying to restrain a concert-goer at the Astroworld Festival in Houston, Texas.
A criminal investigation is underway after the deaths of at least eight people following a crowd surge during Travis Scott's headline set at the music event's opening night.
Houston Police Chief Troy Finner told reporters the security officer "felt a prick in his neck" before falling unconscious and having to be revived by medical staff.
