Met Police has issued an appeal to find a 14-year-old girl who has been missing for over a week.
Isis, from Ashford in Kent, was last seen on Leyton High Road, Stratford, at around 9.30am on Monday, October 13.
The teenager is believed to have travelled by train from Ashford to London early that morning.
Now over a week on, police fear the teenager may have travelled outside of London.
They have appealed to anyone who may have information about her whereabouts to come forward.
Isis is around 5ft 1ins, has cropped black hair and was last seen wearing a white T-shirt, ripped blue jeans and a black coat with a fur-trimmed hood.
Her mother, Vicky, said: "Our world has stood still since Isis went missing, and we desperately want her back home and safe.
"If you have any information, no matter how small, that could help us find her then I urge you to please contact the police.
"Even the smallest detail could make a difference."
Detective Inspector Martin Enever, of the Met's North East Command Unit, said: "We, and Isis' family, are becoming increasingly concerned for her welfare.
"Even if you live outside London, take a close look at the photo of her.
"If you recognise her or have any information please contact us urgently on 101, quoting CAD 1498/15OCT. If you see her, dial 999 immediately and quote the same reference."
