This is TELL ME MORE from NPR News. I'm Celeste Headlee. Michel Martin is away. Coming up, journalist Paul Salopek started walking a while ago. He'll keep walking for seven years. He's following the development of mankind from Ethiopia all the way to the bottom of South America. And we'll talk about how students in cities across the U.S. are falling in his footsteps. That's in a few minutes.
A very disturbing story is emerging from the U.K.:
-- "Two people have been arrested as part of an investigation into slavery and domestic servitude at a house in London sparked by a report on Sky News. The inquiry was launched after one of three alleged victims told a charity she had been held against her will for more than 30 years." (Sky News)
