The Open Championship became the latest high-profile sporting event to be targeted by Just Stop Oil protestors after eco-zealots interrupted play on Friday.
Just Stop Oil activists had already launched protests at the World Snooker Championship, Wimbledon and the Ashes this summer, with England cricket star Johnny Bairstow even forced to remove one individual from the field himself at Lord's.
And now protestors have struck again at The Open, which got underway at Royal Liverpool 24 hours beforehand on Thursday.
Members of the group stormed onto the course to release an orange flare during the 17th hole at Hoylake, before security quickly intervened to stop them.
