The parents of a 15-year-old East Sussex girl who is believed to have gone to France with a man she knows have urged her to contact them.
Megan Stammers, from Eastbourne, was reported missing when she failed to turn up for school on Friday.
Sussex Police said she was spotted later using a Dover to Calais ferry.
Detectives named the man thought to be with Megan as Jeremy Forrest, 30, from Ringmer, near Lewes who was driving a Ford Focus, registration GJ08 RJO.
The teenager's father, Martin, said: "We just want Megan to make contact with us. We are worried and miss her terribly - please get in touch Megan."
Det Insp Andy Harbour from Sussex Police said: "We do not believe Megan to be at risk but we are appealing for her to make contact with her family who are very worried and miss her.
"We know that she crossed from Dover to Calais at around 21:20 BST [on Friday]. We believe she is still in France and we are in contact with the French authorities."
He urged anyone with information about her disappearance to contact police.
