The parents of Megan Stammers have made an emotional plea for her to return home.

The search continues for the 15-year-old schoolgirl who is believed to have run away with a 30-year-old man who is one of her teachers.

On Sunday the police 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.

There have been no reported sightings or contact with the pair since they vanished, and Sussex Police were last night pursuing "critical lines of inquiry".

The alarm was raised at mid-day 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."

A statement on the website of Bishop Bell C of E School said: "We are extremely concerned about a missing pupil and, if anyone at all has any information, we would urge them to contact the police as a matter of urgency."

Anyone with information is asked to call Sussex Police on 101.
