Police have vowed to search "relentlessly" for the missing schoolgirl Tia Sharp - a week on from her disappearance.
Tia disappeared after leaving her grandmother's home in New Addington, Croydon, to go shopping at about noon last Friday.
A week on, Commander Christine Jones from the Metropolitan Police said an intense search was continuing.
She said: "The search continues, the investigation is well under way."
Commander Jones went on: "We've had some great support from the public.
"Obviously we are exploiting every piece of information coming in and all we would say is if you have any information please, please call us.
"We will continue to search relentlessly for her."
Speaking on Thursday, Tia's uncle David Sharp told reporters: "Everyone is trying to do their best by sticking together and keeping everything tight and supporting each other.
"I don't know what has happened to Tia. I don't want anyone to think the worst has happened to Tia."
In a message to her, he said: "Come home. There is no trouble. Walk through that door."
