The investigation into the couple began after the police were contacted by the Freedom Charity.
One of the women held captive gained access to a phone and called the charity.
She said she had been held at a London home against her will for over 30 years.
“It was a process of just over a week where there were lots of phone calls and they gained the trust of the charity, and by doing that they felt confident to reveal enough information, and obviously the police were involved, and they managed to walk out of the house when nobody was around,” said Freedom Charity’s founder, Aneeta Prem.
Freedom Charity raises awareness for child abuse and forced marriages, and specializes in severe traumas.
The three women are currently being taken care of at the charity.
“They have absolutely nothing now and as a charity we’re trying to support them,” said Prem.
“These women are highly traumatized, having been held in servitude for at least 30 years with no real exposure to the outside world, and, trying to find out exactly what has happened over three decades will understandably take some time,” said Hayland.
The police maintain that the three women are not related. The women are of Malaysian, Irish and British heritage.
One of the women is believed to have been born in the house.
According to the police, the two arrested are believed to be a couple and not of British nationality.
