Parents' hell over missing Milly

Amanda went missing on the way home from school

The parents of missing teenager Amanda Dowler have spoken of their "living hell" in coping with their daughter's disappearance.

Their comments came as new pictures of the missing 13-year-old were released on Sunday.

Police have also revealed Amanda, known as Milly to her friends, might have been spotted at a post office in Suffolk.

Amanda has been missing from her home in Walton-on-Thames, Surrey, for more than six weeks.

It is important we corroborate these unconfirmed sightings with other information we have received

Surrey Police spokeswoman

Amanda's parents Robert and Sally said: "We beg from the bottom of our hearts that if someone knows something they come forward and speak to Surrey Police.

"You wouldn't be able to comprehend how much we need that person to come forward with a vital piece of information.

"Someone out there must know something. It is like a living hell and we need to know where Milly is and what has happened to her."

Police have received more than 100 phone calls since The Sun newspaper put up a £100,000 reward on Saturday for information that results in Amanda being found.

Detectives stressed the possible sighting of Amanda in Suffolk was one of many that have been reported across the UK.

A shop worker alerted police in Ipswich on Saturday after claiming to have seen Amanda changing money at a post office.

Police seized CCTV images from the shopping centre where the post office is based and spent six hours searching for the 13-year-old, but were unable to find her.

A Suffolk Police spokesman said stills from the CCTV footage have been passed to detectives in Surrey who are conducting the search for Amanda.

Police alerted British Transport Police and the ferry port at Harwich as the post office worker said the girl changed £20 into euros.

Renewed appeals

A Surrey police spokeswoman said: "It is important we corroborate these unconfirmed sightings with other information we have received before we put any strength into any of these sightings."

Detectives will go through this information in the next few days and follow up other possible leads, as well as renewing appeals at schools and colleges in the area around Amanda's home.

However, Superintendent Alan Sharp, who is leading the investigation into Amanda's disappearance, said they were still appealing for new information.

Abduction unlikely

"No matter how small or insignificant you think that piece of information is we need genuine callers to contact us. Please don't hesitate to pick up the phone," he said.

Police have said it now seems less likely Amanda was snatched from the street by a stranger on 21 March but said they had not discounted the possibility she may have been abducted.
