LONDON - A 69-year-old Malaysian woman was rescued after being held captive as a domestic slave at a house here for over 30 years.
Also rescued were a 57-year-old Irish woman and a 30-year-old Briton who had been held at a property in Lambeth from childhood, reported Sky News, a UK-based news channel.
All three, who were not related and described by police as "highly traumatised", were taken to a place of safety.
The news channel added that two people - a man and a woman, both 67 - have been arrested as part of an investigation into slavery and domestic servitude.
Meanwhile, AFP, quoting Scotland Yard, said police swooped in after being contacted last month by Freedom Charity, which received a call from a woman stating she was being held against her will.
The movement helps young people to understand forced marriage and honour-based violence.
Police said the woman had contacted the movement after watching a television documentary featuring the group's work.
Freedom Charity founder Aneeta Prem told the British media that it was the 57-year-old Irish woman who phoned the organisation.
