Olivia Campbell, from Bury
Olivia Campbell went to the concert with her best friend Adam Lawler, who is being treated in Manchester Royal Infirmary, but Olivia's mum Charlotte hasn’t been able to reach her daughter.
The 15-year-old’s phone is not ringing and despite calling around hospitals, she’s not been able to find out where she is.
Charlotte, 36, told the Manchester Evening News : “I know where Adam is and I know that Olivia isn’t with him.
“I’ve been told by the police that she’s registered as a missing person.
“She had her phone with her but it’s dead, I don’t know whether she’s lost it in the stampede to get out of there, but she knows by number off by heart so I know she can contact me if she’s able to.”
Charlotte, from Bury, was in bed when she received a call from Olivia’s dad telling her about the incident at the arena.
She said: “He just told me ‘there’s been a bomb at the Arena' so I put the news on straight away.
“I phoned the police but was told to wait as it had only just happened but it’s been a long time now and I’ve still heard nothing.”
Friends and relatives are now going into Manchester to help look out for Olivia.
