Detectives searching for BBC make-up artist Diane Chenery-Wickens will search ancient woodland for shallow graves.

Officers looking for the 48-year-old who is feared murdered are switching to a small section of Ashdown Forest, on the Sussex/ Kent border.

Specialist police officers began were trawling the area at first light on Tuesday.

It is feared Mrs Chenery-Wickens' body may lay in the woodland, made famous by the Winnie the Pooh books.

The officer leading the murder investigation, Detective Chief Inspector Steve Johns, told The Argus last night that he was acting on "specific information".

DCI Johns said: "It's a search based in specific information. How relevant that information is yet to be established."

Mrs Chenery-Wickens' husband, David, 51, who last Thursday was arrested on suspicion of carrying out the murder, was released without charge during the early hours of yesterday morning and is thought to be staying with friends or relatives in Sussex.

Officers continued searching the couple's £500,000 home, called Hazelden Cottage, in Duddleswell, near Crowborough, yesterday.

The Argus has obtained exclusive new photos of Mrs Chenery-Wickens, who has now been missing for twelve days, taken while holidaying in Greece.

A friend told The Argus that Mrs Chenery-Wickens would not have run away as she was very concerned about the health of her elderly parents, especially her father, who live close to her in Crowborough.The friend, who wishes to remain anonymous, said: "She would never do that because she cares about her family too much. She's very sensible, she likes to keep in contact with people and make sure they know where she is." They added that she is "extremely worried" about the safety of Mrs Chenery-Wickens who was reported missing in London on January 24. Her disappearance was reported by Mr Chenery-Wickens when she failed to arrive for a hairdressers appointment at 3pm in Regent Place, London. He claimed he had last seen her at Kensington Olympia train station before she attended a work meeting at the BBC. Detective Chief Inspector Steve Johns, who is in charge of the investigation said: "We want to hear from anyone who had seen or spoken to Diane in the week she went missing.

"The last friend to contact Diane, according to the information we have received, is a female friend who spoke to her on the phone between 5 and 6pm on January 22. Diane was reported missing two days later. We have collected and viewed CCTV in an effort to retrace her steps but at the moment we have not been able to identify Diane on any of the CCTV footage we have received. As far as we are aware, she did not attend the meeting at the BBC on January 24.

"It is out of character for Diane not to be in touch, especially with her parents." If anyone has any information they should contact Sussex Police on 0845 60 70 999
