Fears are growing for a four-year-old girl taken from her home in mid Wales.

It is now four weeks since Estelle Clayton from Brecon was abducted by her father and taken to France.

Dyfed-Powys Police are becoming increasingly concerned for the well-being of the little girl - known as Esti - and have issued a fresh appeal for information.

They have had a photograph of the child and her father made into a poster and will be circulating it to French police stations and camp sites.

The child's mother has renewed her appeal for her safe return, but believes Esti's father, Simon Clayton, may have taken her to live in France permanently.

"We need anyone who might have seen them to come forward, so that we can find Esti," said her mother, Aneta Clayton.

Simon Clayton left a note saying he was taking Esti on holiday

"If anyone saw Simon and Esti on a ferry, or buying petrol somewhere, please contact the police."

Esti went missing after staying with book dealer and former pilot Mr Clayton on 9 April.

He left a note for the child's mother, Aneta, saying he was taking his daughter on a three-week holiday.

Police officers suspect that Mr Clayton - who is from the Hay-on-Wye area - acted to avoid going through a planned court hearing over custody.

Travellers and holidaymakers are now being targeted by police in an effort to trace the father and daughter's movements.

Appeal for help : Esti's mother Aneta

It is believed Mr Clayton and Esti boarded a ferry to Caen in France from Portsmouth on the day they disappeared.

Mr Clayton was due to appear at a court hearing in Brecon on Friday, at which a residence order was granted to Estelle's mother, Aneta.

Officers from Dyfed-Powys Police are appealing to anyone travelling to Europe or Morocco to report any sightings of a red Volkswagen Caravelle, registration number A276 OFJ.
