The World Snooker Championship descended into chaos on Monday when action was halted after a male protester ran from the crowd, interrupted an ongoing game between Joe Perry and Robert Milkins and poured orange powder onto the table.
A female protestor attempted to do the same to the table which was hosting the match between Mark Allen and Fan Zhengyi, but was prevented from doing so after an intervention from referee Olivier Marteel.
South Yorkshire Police announced a 52-year-old man and a 30-year-old woman had been taken into custody shortly after the incident.
