Play was stopped and spectators asked to leave the auditorium after a member of the crowd was taken ill during the first-round match between Judd Trump and Neil Robertson at the UK Championship in York.
With Australian Robertson leading 1-0 and ahead 45-40 during a tense second frame, the referee signalled for the players to go off after someone in the crowd at the Barbican needed assistance.
Shortly afterwards, fans were told to make their way out, as the person received treatment.
A World Snooker Tour statement read: “Play has been suspended as a member of the crowd has been taken ill.”
According to reports, the man was helped by paramedics, but was on his feet, and fans were told they would soon be able to return to their seats.
Following a delay of around 15 minutes, the action resumed.
On the other table, John Higgins had made a promising start as he opened up a 2-0 lead over China’s He Guoqiang, making breaks of 110 and 92.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
Callum Baird, Editor of The National
