Detectives are continuing to investigate a missing person's case in Kent after a teenage girl, who travelled out of the UK through Folkestone, is thought to have made her way to Poland with a friend of her mother's.

Serena Alexander Benson, 13, was last seen when she left her home in Wimbledon at around 7.50am on Friday morning.

Although she told her father who she lives with that she was going to school, she never arrived and has not been seen since.

Her mother lives in Poland.

Police officers say the schoolgirl left the country on a Eurotunnel train from Folkestone and have asked for anyone who may have seen her to come forward.

There are concerns for her welfare.

A Met Police statement said: "Police enquiries have established that Serena left the UK at Folkestone on the morning of May 25 on a Eurotunnel train.

"She was travelling in a car with a female friend of her mother's who is a Polish national who lives in London.

"Detectives are not releasing further details at this stage of the route Serena and the woman have taken, nor of how it has been established that they are in Poland, where Serena's mother lives.

"At this stage, the priority of officers is to confirm Serena's exact whereabouts and confirm that she is safe.

"Any potential offences will be considered in due course."

The force also stated that details of Serena, her mother and the woman who Serena is believed to have travelled with have been provided to the Polish authorities.

Enquiries are ongoing to establish their whereabouts and secure the girl's safety.

She was dressed in her predominantly green school uniform and has not been missing before.

Anyone who may know Serena's whereabouts or who may have seen her as she travelled through Folkestone should call officers at Wandsworth CID on 020 3276 2588 who are investigating.
