According to cnn.com British police have arrested a couple on suspicion of holding three "extremely traumatized" women captive for more than 30 years, Scotland Yard announced Thursday.
One of the women -- a 30-year-old Briton -- "appears to have been in servitude for her entire life," Metropolitan Police Detective Inspector Kevin Hyland said. She and the other two women, a 57-year-old from Ireland and a 69-year-old from Malaysia, have been taken to a place of safety and are being cared for by a charity, police said.
The man and woman arrested are both 67, police said. They were taken into custody at their home in the south London borough of Lambeth and were being held as part of an investigation into slavery and domestic servitude, police said.
Their names were not released, and police said only that they are not British nationals. They were later released on bail.
Hyland said it was an unprecedented case for the Met's Human Trafficking Unit.
"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," he said.
