A woman says she saw a blue tent in the field police were searching this afternoon for Constance Marten's missing baby.

Clare Griffiths, who works at the University of Brighton, saw the tent near Wild Park last week.

Police have cordoned off a section of woodland in the area and aerial footage shows a possible campsite amid the trees.

Officers were searching the area nearby today as the desperate search for the newborn baby continued.

Constance Marten and her partner Mark Gordon, who have been missing since January 5, were found in Brighton on Monday night.

They have been arrested on suspicion of gross negligence manslaughter and police have applied for a 36-hour extension to continue questioning them.

Clare said: “I was reading one of the news articles and saw it mentioned they may have been sleeping in a blue tent."

She was walking her dogs in the fields around the back of Wild Park, in the Hollingdean area of Brighton.

She said: “And then it clicked. I saw a blue tent on the side of the hill late last week, at around two o’clock in the afternoon.

“I was with my partner, walking along the top of the field, and she said ‘what’s that tent doing’

“I thought it was odd because it just stood out. No one ever camps up here.

“I told the police to check the woods as there are decent places for shelter in there. It did stick out because of the colour and you don’t see people camping."

Another woman from Hollingdean, who wished to remain anonymous, said she also saw the tent.

She said: "Last week I walked my dogs quite early round the field. I saw a tent and a guy. He was clearly looking to see if I was looking. He had his hat right down, he was wearing a scarf. I didn't see a baby or a woman.

"As soon as I realised the news I let the police know. When I got up here this morning they had already shut the woods off, which is a relief.

"Occasionally you get a homeless person but this felt different. Now all we can do is keep our fingers crossed."
