The 'Sign of the Times' singer was performing at the Eventim Apollo on Sunday night (29.10.17) as part of his solo world tour when the girl started having her medical emergency.

Harry had been singing a rendition of 'Just a little Bit of Your Heart' - a song he co-wrote for Ariana Grande - when he noticed the fan was struggling in the crowd and halted his music to say: "Is everyone OK? You still with me? Do you want to help her up? If everyone could give her some space. If everyone could chill for one second, we'll get some people."

She was then pulled over the barrier and treated by medics.

The fan who Harry helped is known only as Annie but she logged onto her Twitter account to thank Harry for his assistance and reveal details of the ordeal.

Tweeting under the name @alienwhiteside on her account, she wrote: "Harry Styles stopped his entire show because I got crushed and then watched me being pulled over the barrier ... That was one of the most horrendous panic attack's I've ever had like even the medics were terrified of the state I was in ... Harry is so f***ing pure I can't believe it ... I was literally in the worst state that all I remember was Harry looking at me (sic)"

Praising the One Direction star for his actions and the other gig goers who came to her aid, she added in other tweets: "I feel like s**t but I'm so grateful to harry for having such a pure heart and stopping the show to get security to help me ... Also sooooo grateful to the girls around me who realised what was happening and screamed for security ... Honestly Harry Styles is so talented, all his songs are bops and he's an absolute angel (sic)"

The fan had been devastated to miss the rest of the show because of her panic attack but she managed to get a ticket to see him play his second night at the Eventim Apollo on Monday evening (30.10.17) much to the delight of her fellow Directioners who tweeted her to tell to have the best time.
