Bali Drug Arrests: Rachel Dougall Tells How She 'Cannot Eat Or Sleep'

The British mother arrested in Bali on suspicion of drug trafficking has told how she cannot eat or sleep.

Rachel Dougall, 38, has been hospitalised after reportedly refusing to eat in the wake of her arrest. She told The Daily Telegraph through the walls of her hospital cell she was losing her "marbles."

"I am hallucinating, I can't sleep, I can't eat, I am losing my marbles," she said. "They are talking about things which I cannot even imagine."

Rachel Dougall says she has been set up

On Friday Dougall, who was said to not have slept or eaten for days, was taken for treatment after complaining of feeling ill. Dougall, who could receive the death penalty for the alleged smuggling operation, told the BBC she had been given a sedative on arrival at hospital.

Dougall, who was arrested with her partner Julian Ponder, 43, and Paul Beales, has a six year old daughter, Kitty who is reportedly in the care of the couple's maid and gardener on the island.

The suspects were held in a sting operation after British housewife Lindsay Sandiford, 55, was allegedly caught with 4.8kg of cocaine stuffed in the lining of a suitcase as she arrived on the sunshine island.

Dougall has said she was being treated badly and complained that she had not been able to shower.

The mother has maintained her innocence since her arrest, insisting she was the victim of a "fit-up".

Ponder has alleged that he was set up by Sandiford as he went to pick up a birthday present for his daughter.

The Foreign Office said British officials were helping Dougall's daughter as well as the arrested Britons.

Customs officials have said that Mrs Sandiford, originally from Redcar, Teesside, may be spared the death sentence because she helped catch three other members of the smuggling operation, who could face a firing squad.

Police have 60 days before they have to hand over their files to prosecutors, it is believed

Mrs Sandiford is thought to have told police she only agreed to make the smuggling trip because her children in England were being threatened.

She was paraded at a press conference wearing an orange prison T-shirt, flanked by masked, armed officers in Kuta, a town on the holiday island, while a customs official cut open packages wrapped in brown tape to reveal a white powder.

A friend of Sandiford told ITV's Daybreak on Tuesday she remembered her as "someone that helped me", adding she was "very surprised" at her arrest abroad.

"Our children played rugby for Cheltenham and, because I wasn't driving at the time, she'd transport my children, so I helped her with jobs around the house," she said.

"I just can't believe that she's gone that low. I'm just gobsmacked."

Another 68g of cocaine, 280g of powdered ecstasy and a small amount of hashish were also seized following the arrest of the other gang members at separate locations in Bali, officials said.
