The One Direction hunk was almost reduced to tears yesterday (30.06.13) when security guards lost control of a crowd of screaming girls outside his accommodation in New York City and he was forced to drop to his hands and knees and shuffle to his car.
An onlooker told omg!: "Harry looked really upset and scared. Security cleared a path for him but one girl threw herself at him and the rest followed.
"He had to crawl under someone's legs to get into his car, security were going crazy and Harry looked like he was going to cry."
The 19-year-old singer - who is currently on the band's 'Take Me Home' world tour - lost his temper with an enthusiastic admirer after she tugged on his arm and begged him for a photograph before ripping her tour guide to shreds in front of him.
One Direction fan @Oh1DStalker tweeted: "omg a fan just met harry and he wouldn't take a picture so she ripped apart her poster in front of him oh my god.
"She grabbed his arm and said, 'Harry can I take a picture?' And he was like, 'You're not taking a picture by grabbing my arm.'
"He was nice to every single fan until she groped his arm (sic)"
Harry later returned to the hotel and pleaded with the group of followers to leave him alone - and offered to have his photo taken with everyone if they left after getting a memento.
A source explained: "When he arrived back he asked everyone if they would leave if he posed for a picture with each of them.
"Everyone agreed and he spent ages taking pictures after they all got in a line."
