The parents of a missing teenager have made an emotional appeal for the safe return of their daughter, a week after she disappeared.
Leah Croucher was last seen by her family in Milton Keynes late on February 14.
She was picked up by CCTV the following morning, but since then there's been no sign of her.
Police have made extensive searches of the area, including a lake.
At an emotional press conference on Friday, her parents, Claire and John Croucher, said that it was "unbelievable" that she hadn't made contact and directly appealed for her to come home.
"It's unbelievable to her family and friends that she would choose not to contact any of us for the past seven days in any of the formats that are available to the youth of today," Leah's mum Claire said.
"She would not wish to cause worry or the fuss that has arisen due to her highly unusual disappearance.
"We're beside ourselves with worry. Please come home, you're not in any trouble because we love you so much. You're not alone. You will never be alone as long as me and dad are here."
The last confirmed sighting of Leah was taken at 8.15am in Buzzacott Lane in the Furzton area of Milton Keynes on her usual route to work.
Police have described her disappearance as totally out of character and are urging for anyone who may have seen Leah or has any information to come forward.
"Leah's disappearance is highly unusual," Ch Insp Neil Kentish told ITV News Anglia.
"She's a creature of habit and walks to work from her home in Emerson Valley to her place of work in Knowlhill every day. She's now vanished.
"I need the public to come forward with any information. This is very much a missing persons investigation. We have an open mind, as we do with every missing persons investigation. I've got a dedicated team of 50 people out there looking for Leah, but again, it's about the public helping us."
The police appeal will be shown on big screens at Saturday's League Two football match between MK Dons and Newport County, and Leah's family will join officers in handing out leaflets as they continue to try to find their girl.
