Police have appealed to trace a missing schoolgirl who left the UK on a EuroTunnel train.

Serena Alexander-Benson, 13, was last seen by her father leaving their home in Wimbledon, south-west London, at around 7.50am on Friday.

Dressed in her mostly green school uniform, her father reported she had told him she was going to school, but she did not arrive.

She has not been reported missing before and, while she lives in London with her father, her mother lives in Poland, the Metropolitan Police said.

It is understood she went through passport control and is thought to be “probably in the company of an older person”.

Officers believe the teenager left the country from Folkestone, in Kent, on Friday morning and appealed for anyone who saw her to come forward.
