A charity has reiterated the importance of learning potentially life-saving CPR after a Newcastle United fan collapsed during a match.
Sergio Petrucci, the founder of the Red Sky Foundation, said that time is of the essence when dealing with someone suffering from a sudden cardiac arrest and urged people to learn CPR.
It comes after Newcastle fan Alan George Smith went into cardiac arrest during the first half of the Premier League clash with Tottenham on October 17.

Medics in the crowd rushed to help the 80-year-old supporter in the East Stand at St James' Park, with their speedy actions thought to have been vital in his survival.
His family said Alan is making "great progress" and have said they will be "forever grateful" for those who have given him medical treatment.
Reacting to the efforts by staff, players and fans, Sergio said: "My immediate reaction was I hope this man is going to be okay but second to that, he couldn't have been in a better place.
"The most important thing with a sudden cardiac arrest is time so it's important call 999 for help straight away and when you've got 52,000 Geordies screaming for help he couldn't have been in a better place.
"Hearing about the people that rushed to his aid, they are his guardian angels.
"The main thing is, this guy survived. I know so many people that didn't because they had not been able to be rescued."
Sergio and Emma Petrucci were inspired to set up the Sunderland-based charity Red Sky Foundation after their daughterâ€™s life was saved by doctors in 2015.
As well as raising money for defibrillators, the charity also raises awareness of CPR and often goes into schools to teach engaging lessons with children.
Sergio said: "Time is of the essence and that's what we try to stress with the Red Sky Foundation when we're going into schools or doing community work.
"We also talk about the importance of teamwork and going back to the Newcastle United fan, everyone worked as a team.
"CPR can go on for five, ten, 30 minutes and it can be exhausting. Life is about working as a team it's not about being an individual in whatever career path you go down teamwork is crucial.
"Going back to time being of the essence, after four minutes the brain starts to die and your chance of survival drops with every minute that passes.
"We also aim to get a defibrillator every 500 metres."
Sergio stressed that even if you don't feel confident doing CPR, doing something is always better than doing nothing.
He said: "Anyone can do CPR. People think they're going to hurt them by doing it by you can't do any more harm than what's happening at the moment.
"They just need the confidence to do it. Doing something is better than doing nothing as that person will die.
"Like with Christian Eriksen, everybody was glued to the TV listening to the pundits and all the feedback but being in a very public place like a football game or shopping centre it's the best place to be.
"Only one in ten people survive out of hospital cardiac arrests. Everything thinks of cancer as the biggest killer but cardiac arrests are right up there."
