The search is continuing for a 15-year-old schoolgirl who is believed to have run away with a 30-year-old man who is one of her teachers.
Police have appealed to Jeremy Forrest or Megan Stammers to make contact after eloping across the English Channel.
It is believed that Mr Forrest is a maths teacher at the same school that Megan attends, Bishop Bell C of E School in Eastbourne, East Sussex. There have been no reported sightings or contact with the pair since they vanished, and Sussex Police said they are pursuing "critical lines of inquiry".
The alarm was raised at midday on Friday after Megan failed to turn up for school. Nine hours later she crossed from Dover to Calais, sparking an appeal to trace her. Police have said they do not believe Megan is at risk but they are in contact with the French authorities in an effort to reunite her with relatives.
Her father Martin Stammers said on Saturday: "We just want Megan to make contact with us. We are worried and miss her terribly. Please get in touch, Megan." Appeals for information about her whereabouts have been posted on Facebook and Twitter, including from her worried father. He tweeted: "Have to remain strong for Meg's, can't dwell in the misery of 'what ifs' - we love you sweetheart, doing all we can #findmeganstammers."
A website - www.meganstammers.com - has also been set up to appeal for information about Megan's whereabouts. Officers have appealed for information about the whereabouts of a black Ford Fiesta, registration GJ08 RJO, driven by Mr Forrest, from Ringmer, near Lewes.
On a blog apparently written by Mr Forrest under his music stage name Jeremy Ayre, he writes about a "moral dilemma" in a posting four months ago headed: "You hit me just like heroin...".
Posted online on May 19, it states: "The last two weeks have been pretty intense, in both a good and a bad way!!!
"About a week ago I had a bit of a moral dilemma to deal with, both internally and externally. And the over-riding question it left me with was this: How do we, and how should we, define what is right or wrong, acceptable or unacceptable???
"I came to a few different conclusions, mainly that actually we get a lot of things wrong, but at the end of the day I was satisfied that if you can look at yourself in the mirror and know that, under all the front, that you are a good person, that should have faith in your own judgment. That's some philosophical gold for you there!!!"
