Just quoting bbc at this point:
Sounded like gunshots'
Jade Baynes, who is from Hull, said she was told to run by armed police after leaving the arena.
The 18-year-old said she heard loud bangs and what sounded like gunshots just after the concert had finished.
She added: "There were just a loud bang and a flash and everyone tried to scramble out.
"An alarm came on telling everyone to stay calm but leave as quickly as possible."
