Lambeth 'slaves': The women freed after 30 years in London house

Three ‘deeply traumatised’ victims rescued in Lambeth include one who has been a captive all her life

It was a call to the Freedom Charity that marked the beginning of the end. The emotional woman said that her “friend” was only ever allowed out of the home to hang washing out and occasionally walk to a shop under the tight control of one of their alleged captors. The call last month began a painstaking operation to extricate three “absolutely terrified” women from a house in the heart of London where they were allegedly held for at least 30 years, in what police said could be Britain’s most enduring case of domestic slavery.

One of the women, who were all described as being “deeply traumatised”, is believed to have been kept in the same house in the borough of Lambeth for her entire life and deprived of any “normal” contact with the outside world since she was a baby.

The Independent understands that another of the victims was deprived of medical treatment despite telling her alleged captors – who were seen as “heads of the family” – that she believed she had suffered a stroke.

Officers from Scotland Yard’s human trafficking unit staged a dawn raid on the women’s home – described by charity workers as “an ordinary house on an ordinary street” – and arrested a man and a woman, both aged 67, on suspicion of slavery and forced domestic servitude. Today they were released on bail until a date in January, Scotland Yard said. Their alleged captives – a 30-year-old Briton, a 69-year-old Malaysian and a 57-year-old Irish woman – were released by police and staff from the London-based Freedom Charity several weeks ago.

Such is the women’s fragile state that officers have had to spend days piecing together details of their alleged ordeal before moving in to make arrests. Scotland Yard said the suspects were “not British nationals” but gave no more details.

The call that ended their apparent captivity came after one of the two older women had watched a documentary about forced marriage which focused on the Freedom Charity; she used a freephone number at the end of the programme to contact astonished welfare workers.

Detective Inspector Kevin Hyland, who is leading the investigation, said the women’s alleged servitude was three times longer than anything seen before by police.

He said: “We have launched an extensive investigation [into] these very serious allegations. All three women were deeply affected and traumatised. Their lives were greatly controlled, and for much of [the time] they would have been kept on the premises.

“We have had some previous cases...where we know people have been held against their will for up to 10 years. We have never seen anything of this magnitude.”

The Yard said many details of the women’s lives over the past three decades, including how they came to be held in the house in the first place, remained unclear because of the trauma they had suffered.

Officers are debriefing the women at accommodation provided by the charity, slowly building up a picture of a life where their every move is claimed to have been scrutinised and any contact with the outside world tightly restricted. The house where they were allegedly held was being searched.

The case was immediately compared to that of Josef Fritzl, the Austrian man who kept his daughter captive for 24 years and fathered seven children with her. However, these three women are not related and officers said they had no information that the youngest was related to the two people under arrest. Police said they were not investigating sexual abuse allegations.

The Independent understands that although the women were not kept permanently in the house, their access to the outside world consisted of being allowed to hang out laundry and occasional shopping trips while accompanied by one of their alleged captors.

Aneeta Prem, a magistrate and founder of Freedom Charity, which helps victims of forced marriage and “honour” violence, said that after the initial call, welfare workers and police were able to identify the women’s home and set up clandestine meetings.

It is believed the women suffered physical as well as mental harm. Ms Prem told Sky News: “We started in-depth talks with them when they could; it had to be pre-arranged. They gave us set times when they were able to speak to us. It was planned that they would be able to walk out of the property. The police were on standby.”

The charity said the women had described their claimed captors as “heads of the family” and were living in a state of terror. Ms Prem said: “They felt they were in massive danger. I don’t believe the neighbours knew anything about it at all. It was just an ordinary house in an ordinary street.”

Police said they did not yet know if the 30-year-old had been born in the house but it was clear it had been her home ever since.

The Independent understands that the initial caller spoke of a “friend” and did not immediately identify herself or the other two women as victims of domestic slavery.

It is thought that the woman did not give names or an address. The caller, who was in an emotional state, said that the “friend” believed she had suffered a stroke and knew she was not well, but she was not allowed medical help. The caller said the “friend” had had no education at the address.

In a report, the Centre for Social Justice said that in 2012 about 800 adults were known to have been enslaved in the UK, but it said this figure was a “pale reflection” of the true scale of the problem.

Adults and children were exploited through the sex industry, domestic servitude and enforced criminal activity. The charity said its research showed that many cases were never recognised or reported and that it had no consistent grip on the numbers. “Agencies charged with such responsibility are groping in the dark for a sense of scale,” it said.

“It was planned that they would be able to walk out of the property. The police were on standby.

“They were able to leave the property, but it was done in such a way... it was a very, very excellent way it happened.”

Ms Prem said the two people arrested were considered the “heads of the family”, and that the women were “absolutely terrified” of them.

She added: “They felt they were in massive danger. I don't believe the neighbours knew anything about it at all. It was just an ordinary house in an ordinary street.

“They were very restricted on everything they could do.

“We are absolutely thrilled this has happened.”

Detective Inspector Kevin Hyland, from the Met's human trafficking unit, said: “ We've established that all three women were held in this situation for at least 30 years. They did have some controlled freedom.

”The human trafficking unit of the Metropolitan Police deals with many cases of servitude and forced labour. We've seen some cases where people have been held for up to 10 years but we've never seen anything of this magnitude before."

Mr Hyland said there was a delay in arresting the suspects, who are both non-British, after the women were freed on October 25 as police tried to establish the facts of the case.

“The women were released as soon as possible,” he said.

“There was a delay in the arrest. This was down to the fact that we had to work very carefully with these people who were highly traumatised and it was very difficult to establish the facts.

Asked about what help the women will be given, the charity founder said: “They are going to be afforded all the help and support that can be.

“I'm so grateful they saw the news. Now they will try to re-build their lives.”
