Three women enslaved for 30 years have been rescued from a house in London including one who has spent her entire life in domestic servitude, according to Reuters.

Officers, who arrested a man and a woman, both 67, at their south London home, described it as the worst case of servitude to have emerged in the British capital.

A 69-year-old Malaysian, a 57-year-old from Ireland and a 30-year-old Briton appeared to have had limited freedom over the years but it was not until one victim summoned the courage to call a charity on October 18 after watching a BBC documentary featuring an anti-slavery campaigner that they came to light.

After building trust with workers at Freedom Charity, the two younger women met with charity staff and police on October 25 and led them to the house where they rescued the third woman and all three were taken to safety.

The police arrested two people described as non-British nationals on suspicion of being involved in forced labor and domestic servitude. The man and woman remain in custody.
