Police have been carrying out house-to-house inquiries in Brixton in South London today, as more details emerge about the three women apparently held as slaves there for 30 years.
More has also been revealed about their alleged captors.
Detectives now believe the group initially lived together in some kind of "collective" and shared a political ideology. But although that ended, they stayed together and the victims faced emotional and physical abuse.
The founder of the charity that helped the alleged slavery victims has said there has been an "extraordinary rise in calls" to its helpline since the rescue of the women came into the public domain.
Aneeta Prem of the Freedom Charity added: "We received five times as many calls in 24 hours as we normally do in one week and are needing to increase our resources to cope with this extra demand.
"These women have had traumatic and distributing experiences, which they have revealed to us. What needs to happen now is that the three victims, who have begun a long process of recovery, are able to go through their rehabilitation undisturbed, without being identified."
Three women allegedly held for 30 years at a south London address were "emotionally and physically abused", the Metropolitan Police force said today.
In a statement, Commander Steve Rodhouse, said:
The people involved, the nature of that collective and how it operated is all subject to our investigation and we are slowly and painstakingly piecing together more information. I will not give any further information about it.
Somehow that collective came to an end and how the women ended up continuing to live with the suspects. How this resulted in the women living in this way for over 30 years is what [we] are seeking to establish, but we believe emotional and physical abuse has been a feature of all the victims' lives.
One of the women allegedly held captive for decades in a south London home, had lived there all of her life, police said today.
In a statement, Metropolitan Police Commander Steve Rodhouse said:
The 30 year old woman does have a birth certificate; however that is all the official documentation we can find. We believe she has lived with the suspects and the other victims all her life, but of course at this early stage we are still seeking out evidence.
Two suspects held over claims that three women were held captive for 30 years in a London address are of Indian and Tanzanian origin, the Metropolitan Police said today.
Commander Steve Rodhouse added:
The suspects are of Indian and Tanzanian origin that came to the UK in the 1960s. We believe that two of the victims met the male suspect in London through a shared political ideology, and that they lived together at an address that you could effectively call a 'collective'.
The discovery of three women allegedly held as slaves in a south London house is the "tip of a rather large iceberg", according to an MP in charge of reviewing evidence of slavery in Britain.
Frank Field, chair of the Modern Slavery Bill evidence review, said criminal gangs were making "huge sums of money" from people being imported into the UK to work "almost for nothing".
Mr Field was speaking to BBC Breakfast about the case of three women being rescued from a house in Lambeth earlier this week. He said: "I would have thought it's safe to act on the assumption that the examples we've had in the last few months are the tip of a rather large iceberg."
